• Designing a general database interface in PHP

  - by lamas

  I'm creating a small framework for my web projects in PHP so I don't have to do the basic work over and over again for every new website. It is not my goal to create a second CakePHP or Codeigniter and I'm also not planning to build my websites with any of the available frameworks as I prefer to use things I've created myself in general. I have no problems in designing that framework when it comes to parts like the core structure, request handling, and so on but I'm getting stuck with designing the database interface for my modules. I've already thought about using the MVC pattern but thought that it would be a bit of a overkill. So the exact problem I'm facing is how my frameworks modules (viewCustomers could be a module, for example) should interact with the database. Is it a good idea to write SQL directly in PHP (mysql_query( 'SELECT firstname, lastname(.....))? How could I abstract a query like SELECT firstname, lastname FROM customers WHERE id=X Would MySQL helper functions like $this->db->get( array('firstname', 'lastname'), array('id'=>X) ) be a good idea? I suppose not because they actually make everything more complicated by requiring arrays to be created and passed. Is the Model pattern from MVC my only real option?

• function in php for displaying a menu

  - by Stanislas Piotrowski

  I met some trouble with a function I have written. In fact I have an array in which I have different custom values. I would like to display the result of that, so here is my function function getAccess($var){ $data=mysql_fetch_array(mysql_query("SELECT * FROM `acces` WHERE `id`='.$var.'")); return $data; } getAccess($_SESSION['id']); $paramAcces = array( 'comptesfinanciers' => array( 'libelle' => 'COMPTES FINANCIERS', 'acces' => $data['comptesfinanciers'], 'lien' => 'financier', 'image' => 'images/finances.png' ) ); I have done a var_dump of $paramAcces which return array(1) { ["comptesfinanciers"]=> array(4) { ["libelle"]=> string(18) "COMPTES FINANCIERS" ["acces"]=> NULL ["lien"]=> string(9) "financier" ["image"]=> string(19) "images/finances.png" } } (that are the ecpected values). Here is the function for displaying what is in the array /** * AFFICHAGE DE LA SECTION PARAMETRES SUR LA PAGE D'ACCUEIL */ function affichParam($paramAccees){ echo '<ul class="getcash-vmenu"><li><a href="index.php?p='.$paramAccees['lien'].'" class="active"><span class="t"><img src="'.$paramAccees['image'].'"> '.$paramAccees['libelle'].'</span></a></li></ul>'; } The trouble is that actualy it return to me an empty line. I really do not know what I'm wrong doin: I call the function like that: <?php affichParam($paramAccees) ?> In a second time I will add more value, so I think I will have to do a for each loop or something like that. But actualy I just would like to display the first record. Any kind of help will be much apprecitaed

• Stored Procedure: Variable passed from PHP alters second half of query string

  - by Stephanie

  Hello everyone, Basically, we have an ASP website right now that I'm converting to PHP. We're still using the MSSQL server for the DB -- it's not moving. In the ASP, now, there's an include file with a giant sql query that's being executed. This include sits on a lot of pages and this is a simple version of what happens. Pages A, B and C all use this include file to return a listing. In ASP, Page A passes through variable A to the include file - page B passes through variable B -- page C passes through variable C, and so on. The include file builds the SQL query like this: sql = "SELECT * from table_one LEFT OUTER JOIN table_two ON table_one.id = table_two.id" then adds (remember, ASP), based on the variable passed through from the parent page, Select Case sType Case "A" sql = sql & "WHERE LOWER(column_a) <> 'no' AND LTRIM(ISNULL(column_b),'') <> '' ORDER BY column_a Case "B" sql = sql & "WHERE LOWER(column_c) <> 'no' ORDER BY lastname, firstname Case "C" sql = sql & "WHERE LOWER(column_f) <> 'no' OR LOWER(column_g) <> 'no' ORDER BY column_g As you notice, every string that's added on as the second part of the sql query is different than the previous; not just one variable can be substituted out, which is what has me stumped. How do I translate this case / switch into the stored procedure, based on the varchar input that I pass to the stored procedure via PHP? This stored procedure will actually handle a query listing for about 20 pages, so it's a hefty one and this is my first major complicated one. I'm getting there, though! I'm also just more used to MySQL, too. Not that they're that different. :P Thank you very much for your help in advance. Stephanie

• Building a CMS in PHP: Development tools

  - by TRiG

  I'm planning to build a CMS in PHP and MySQL, mainly for my own amusement and education. (Though who knows, I may come up with something useful and cool. Anything's possible.) I'll be asking questions about code architecture etc. later. For now, I'm more interested in development tools. So far, all my playing with code has been done on a web server, and I've edited over FTP. I was thinking it might be quicker to use a localhost. Also, that way, I could use version control (which I've never done before). So, A. How do I set up a localhost server with many subdomains on an Ubuntu 9.10 computer. Is XAMPP for Linux the way to go, or should I use a standard Apache distro? (Or another webserver altogether?) For that matter, is it possible to set up more than one webserver on the same computer, and to use them for different localhost subdomains? B. How do I set up a version control thingy covering all the code (which will be on several subdomains of localhost, and in a few shared folders)? I've read Joel Spolsky's HgInt tutorial, and it makes Mercurial look good. And simple, especially if you're working on your own. C. Should I continue to use gEdit to write HTML/CSS/JS/PHP, or is there a better free editor out there for these languages?

• Pass checkbox values with Jquery to PHP and display result in div

  - by user1343955

  I want to filter realtime results with jQuery (just like on this site http://shop.www.hi.nl/hi/mcsmambo.p?M5NextUrl=RSRCH). So when someones checks a checkbox the results should update realtime (in a div). Now I'm a newbie with jQuery and I've tried lots of examples but I can't get it to work. Here's my code, could anyone tell what I'm doing wrong? Thank you very much! HTML <div id="c_b"> Kleur:<br /> <input type="checkbox" name="kleur[1]" value="Blauw"> Blauw <br /> <input type="checkbox" name="kleur[2]" value="Wit"> Wit <br /> <input type="checkbox" name="kleur[3]" value="Zwart"> Zwart <br /> <br /> Operating System:<br /> <input type="checkbox" name="os[1]" value="Android"> Android <br /> <input type="checkbox" name="os[2]" value="Apple iOS"> Apple iOS <br /> </div> <div id="myResponse">Here should be the result</div> jQuery function updateTextArea() { var allVals = []; $('#c_b :checked').each(function() { allVals.push($(this).val()); }); var dataString = $(allVals).serialize(); $.ajax({ type:'POST', url:'/wp-content/themes/u-design/filteropties.php', data: dataString, success: function(data){ $('#myResponse').html(data); } }); } $(document).ready(function() { $('#c_b input').click(updateTextArea); updateTextArea(); }); PHP //Just to see if the var passing works echo var_export($_POST);

• Resolve php "deadlock"

  - by Matt

  Hey all, I'm currently running into a situation that I guess would be called deadlock. I'm implementing a message service that calls various object methods.. it's quite similar to observer pattern.. Here's whats going on: Dispatcher.php Dispatcher.php <? class Dispatcher { ... public function message($name, $method) { // Find the object based on the name $object = $this->findObjectByName($name); // Slight psuedocode.. for ease of example if($this->not_initialized($object)) $object = new $object(); // This is where it locks up. } return $object->$method(); ... } class A { function __construct() { $Dispatcher->message("B", "getName"); } public function getName() { return "Class A"; } } class B { function __construct() { // Assume $Dispatcher is the classes $Dispatcher->message("A", "getName"); } public function getName() { return "Class B"; } } ?> It locks up when neither object is initialized. It just goes back and forth from message each other and no one can be initialized. Any help would be immensely helpful.. Thanks! Matt Mueller

• Get number of posts in a topic PHP

  - by Wayne

  How do I get to display the number of posts on a topic like a forum. I used this... (how very noobish): function numberofposts($n) { $sql = "SELECT * FROM posts WHERE topic_id = '" . $n . "'"; $result = mysql_query($sql) or die(mysql_error()); $count = mysql_num_rows($result); echo number_format($count); } The while loop of listing topics: <div class="topics"> <div class="topic-name"> <p><?php echo $row['topic_title']; ?></p> </div> <div class="topic-posts"> <p><?php echo numberofposts($row['topic_id']); ?></p> </div> </div> Although it is a bad method of doing this... All I need is to know what would be the best method, don't just point me out to a website, do it here, because I'm trying to learn much. Okay? :D Thanks.

• Help a Beginner with a PHP based Login System

  - by Brian Lang

  I'm a bit embarrassed to say, but I've run into issue with creating a PHP based login system. I'm using a site template to handle the looks of the the login process, so I will spare you the code. Here is my thought process on how to handle the login: Create a simple login.php file. On there will be a form whose action is set to itself. It will check to see if the submit has been clicked, and if so validate to make sure the user entered a valid password / username. If they do, set a session variable save some login info (username, NOT password), and redirect them to a restricted area. If the login info isn't valid, save an error message in a session variable, display error message giving further instruction, and wait for the user to resubmit. Here is a chunk of what I have - hopefully one of you experts can see where I've gone wrong, and give me some insight: if(isset($_POST['submit'])) { if(!empty($_POST['username']) AND !empty(!$_POST['password'])) { header("Location: http://www.google.com"); } else { $err = 'All the fields must be filled in!'; } } if($err) { $_SESSION['msg']['login-err'] = $err; } ? Now the above is just an example - the intent of the above code is to process user input, with the script validating simply that the user has given input for username and password. If they have, I would like them, in this case, to be redirected to google.com (for the sake of this example). If not, save an error message. Given my current code, the error message will display perfectly, however if the user submits and has something entered for the username and password, the page simply doesn't redirect. I'm sure this is a silly question, but I am a beginner, and well, to be honest, a bit buzzed right now. Thanks so much!

• How to store multiple cookies through PHP Curl

  - by Ahmad

  'SOUP.IO' is not providing any api. So Iam trying to use 'PHP Curl' to login and submit data through PHP. Iam able to login the website successfully(through cUrl), but when I try to submit data through cUrl, it gives me error of 'invalid user'. When I tried to analysed the code and website, I came to know that cUrl is getting values of only 1-2 cookies. Where as when I open the same page in FireFox, it shows me 6-7 cookies related to 'SOUP.IO'. Can some one guide me how to get all these 7 cookies values. Following cookies are getable by cUrl: soup_session_id Following cookies are shown in Firefox (not through cUrl): __qca, __utma, __utmb, __utmc, __utmz Following is my cUrl code: $cookie_file_path = getcwd()."/cookie/cookie.txt"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://www.soup.io'); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_HEADER, TRUE); curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate'); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) FirePHP/0.4'); curl_setopt($ch, CURLOPT_MAXREDIRS, 10); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $result = curl_exec($ch); curl_close($ch); print_r($result); ?

• after .htaccess url rewrite, cannot perform logoff in some of the url rewrited page

  - by Patrick

  Recently, I was doing .htaccess url rewrite, make all my php url into html, in some page, the logout button wont work properly. for example, in page ‘quotedetails/Q9999.html’ (rewrited from ‘quotedetails.php?quoteID=Q9999'), when I click logout button in this page, it wont do the trick, but when i use the old php url of this page, it works again, other rewrited pages like index.html (index.php), search.html(search.php), all works perfectly. I use firebug to debug, after I click the logout button, it stays in the same page without redirect me to the index.html, but I saw the the ‘logoff’ params has been passed through, but just dont let me logout and redirect to index page. I’ve changed all the relavent file path to absolute path, still no luck…..help please. I’ve also noticed from firebug, that page cannot get the redirect ‘location’ as I tried in other pages, their response headers come with ‘location: index.html’, but in that no-workin-page, there is no such line called ‘location: index.html’ in its response headers. Here is my .htaccess file, no-workin-pages are related to the first four ReweiteRules Options +FollowSymlinks RewriteEngine on RewriteRule ^reps/all,all.html$ rep.php?repID=all&repName=all RewriteRule ^reps/([A-Z]+),([A-Za-z\sA-Za-z]+).html$ rep.php?repID=$1&repName=$2 RewriteRule ^reps/([A-Za-z]+),([A-Za-z\sA-Za-z]+),([0-9]+).html$ rep.php?repID=$1repName=$2&page=$3 RewriteRule ^quotedetails/(Q[0-9]+).html$ quotedetails.php?quoteID=$1 RewriteRule ^index.html$ index.php RewriteRule ^addquote.html$ addquote.php RewriteRule ^search.html$ search.php RewriteRule ^viewall.html$ viewall.php RewriteRule ^howto.html$ howto.php

• PHP RegEx: How to Stripe Whitespace Between Two Strings

  - by roydukkey

  I have been trying to write a regex that will remove whitespace following a semicolon (';') when it is between both an open and close curly brace ('{','}'). I've gotten somewhere but haven't been able to pull it off. Here what I've got: <?php $output = '@import url("/home/style/nav.css"); body{color:#777; background:#222 url("/home/style/nav.css") top center no-repeat; line-height:23px; font-family:Arial,Times,serif; font-size:13px}' $output = preg_replace("#({.*;) \s* (.*[^;]})#x", "$1$2", $output); ?> The the $output should be as follows. Also, notice that the first semicolon in the string still is followed by whitespace, as it should be. <?php $output = '@import url("/home/style/nav.css"); body{color:#777;background:#222 url("/home/style/nav.css") top center no-repeat;line-height:23px;font-family:Arial,Times,serif;font-size:13px}'; ?> Thanks! In advance to anyone willing to give it a shot.

• Getting XML Numbered Entities with PHP 5 DOM

  - by user343607

  Hello guys, I am new here and got a question that is tricking me all day long. I've made a PHP script, that reads a website source code through cURL, then works with DOMDocument class in order to generate a sitemap file. It is working like a charm in almost every aspect. The problem is with special characters. For compatibility reasons, sitemap files needs to have all special chars encoded as numbered entities. And I am not achieving that. For example, one of my entries - automatically read from site URLs, and wrote to sitemap file - is: http://www.somesite.com/serviços/redesign/ On the source code it should looks like: http://www.somesite.com/servi*ç*os/redesign/ Just this. But unfortunately, I am really not figuring it out how to do it. Source code file, server headers, etc... everything is encoded as UTF-8. I'm using DOMDocument and related extensions to build the XML. (Basically, DOMDocument, $obj-createElement, $obj-appendChild). htmlentities gives ç instead of ç str_replace does not work. It makes the character just vanish in the output. I was using $obj-createElement("loc", $url); on my code, and just now I read in PHP manual that I should use $document-createTextNode($page), in order to have entities encoding support. Well, it is not working either. Any idea on how to get unstuck of this? Thanks.

• Good PHP / MYSQL hashing solution for large number of text values

  - by Dave

  Short descriptio: Need hashing algorithm solution in php for large number of text values. Long description. PRODUCT_OWNER_TABLE serial_number (auto_inc), product_name, owner_id OWNER_TABLE owner_id (auto_inc), owener_name I need to maintain a database of 200000 unique products and their owners (AND all subsequent changes to ownership). Each product has one owner, but an owner may have MANY different products. Owner names are "Adam Smith", "John Reeves", etc, just text values (quite likely to be unicode as well). I want to optimize the database design, so what i was thinking was, every week when i run this script, it fetchs the owner of a proudct, then checks against a table i suppose similar to PRODUCT_OWNER_TABLE, fetching the owner_id. It then looks up owner_id in OWNER_TABLE. If it matches, then its the same, so it moves on. The problem is when its different... To optimize the database, i think i should be checking against the other "owner_name" entries in OWNER_TABLE to see if that value exists there. If it does, then i should use that owner_id. If it doesnt, then i should add another entry. Note that there is nothing special about the "name". as long as i maintain the correct linkagaes AND make the OWNER_TABLE "read-only, append-new" type table - I should be able create a historical archive of ownership. I need to do this check for 200000 entries, with i dont know how many unique owner names (~50000?). I think i need a hashing solution - the OWNER_TABLE wont be sorted, so search algos wont be optimal. programming language is PHP. database is MYSQL.

• PHP webservice for c# application

  - by user293995

  Hi, I want to create a php webservice server to be used from a C# application. I want to have a library who autogenerate wsdl file for easy management (That's the reason why I choosed NuSoap). I tried to use nusoap on PHP5. I have some problems with charset and Content-Type. Visual Studio gives this error : The HTML document does not contain Web service discovery information. Metadata contains a reference that cannot be resolved: 'https://www.xxx.yy'. There is a problem with the XML that was received from the network. See inner exception for more details. The encoding in the declaration 'ISO-8859-1' does not match the encoding of the document 'utf-8'. If the service is defined in the current solution, try building the solution and adding the service reference again. $soap= new soap_server(); $soap-xml_encoding = 'utf-8'; $soap-configureWSDL('Bonjour', 'https://www.xxx.yy'); $soap-wsdl-schemaTargetNamespace = 'http://soapinterop.org/xsd/'; $soap-register('bonjour', array('prenom' = 'xsd:string')); $HTTP_RAW_POST_DATA = file_get_contents("php://input"); $soap-service($HTTP_RAW_POST_DATA); header('Content-Type: application/soap+xml; charset=utf-8'); function bonjour($prenom) { return "Bonjour ".$prenom; } ? Does someone knows how to change that to make it compliant and working ? Thanks

• PHP: Post ASPX form that uses 'WebForm_DoPostBackWithOptions' with cUrl

  - by Oliver Cooper

  I am trying to post an ASPX form which uses SharePoint with PHP. Posting data works with standard forms, I just can't seem to get this form working. I did notice an onclick attribute on the submit button: onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$PlaceHolderMain$btnSaveTask", "", true, "", "", false, false))" I have never used ASPX and have no idea what this is. It is not an authentication problem or something wrong with the url as it returns the webpage (which contains the form) fine. Here is my PHP code: function add($username, $password){ $data = array( 'ctl00$PlaceHolderSearchArea$ctl01$ctl00' => 'https://keystone.stpeters.sa.edu.au', 'ctl00$PlaceHolderSearchArea$ctl01$ctl04' => '0', 'ctl00$PlaceHolderMain$DateStart$DateStartDate' => '9/05/2012', 'ctl00$PlaceHolderMain$DateDue$DateDueDate' => '10/05/2012', 'ctl00$PlaceHolderMain$Title' => 'test again', 'ctl00$PlaceHolderMain$btnSaveTask' => 'OK', '__spText1' => '', '__spText2' => '' ); $curl_handle = curl_init(); $fullurl = "https://keystone.stpeters.sa.edu.au/_layouts/StPeters.Keystone/MyTasks/MyTaskDetail.aspx?id=0&IsDlg=1"; // $ch = curl_init(); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_FAILONERROR, 0); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($ch, CURLOPT_USERPWD, "$username:$password"); curl_setopt($ch, CURLOPT_URL, $fullurl); $returned = curl_exec($ch); curl_close ($ch); return $returned; }

• Initializing PHP class property declarations with simple expressions yields syntax error

  - by user171929

  According to the PHP docs, one can initialize properties in classes with the following restriction: "This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated." I'm trying to initialize an array and having some issues. While this works fine: public $var = array( 1 => 4, 2 => 5, ); This creates a syntax error: public $var = array( 1 => 4, 2 => (4+1), ); Even this isn't accepted: public $var = 4+1; which suggests it's not a limitation of the array() language construct. Now, the last time I checked, "4+1" equated to a constant value that not only should be accepted, but should in fact be optimized away. In any case, it's certainly able to be evaluated at compile-time. So what's going on here? Is the limitation really along the lines of "cannot be any calculated expression at all", versus any expression "able to be evaluated at compile time"? The use of "evaluated" in the doc's language suggests that simple calculations are permitted, but alas.... If this is a bug in PHP, does anyone have a bug ID? I tried to find one but didn't have any luck.

• how to implement enhanced session handling in PHP

  - by praksant

  Hi, i'm working with sessions in PHP, and i have different applications on single domain. Problem is, that cookies are domain specific, and so session ids are sent to any page on single domain. (i don't know if there is a way to make cookies work in different way). So Session variables are visible in every page on this domain. I'm trying to implement custom session manager to overcome this behavior, but i'm not sure if i'm thinking about it right. I want to completely avoid PHP session system, and make a global object, which would store session data and on the end of script save it to database. On first access i would generate unique session_id and create a cookie On the end of script save session data with session_id, timestamps for start of session and last access, and data from $_SERVER, such as REMOTE_ADDR, REMOTE_PORT, HTTP_USER_AGENT. On every access chceck database for session_id sent in cookie from client, check IP, Port and user agent (for security) and read data into session variable (if not expired). If session_id expired, delete from database. That session variable would be implemented as singleton (i know i would get tight coupling with this class, but i don't know about better solution). I'm trying to get following benefits: Session variables invisible in another scripts on the same server and same domain Custom management of session expiration Way to see open sessions (something like list of online users) i'm not sure if i'm overlooking any disadvantages of this solution. Is there any better way? Thank you!!

• What is the equivalent to Master Views from ASP.NET in PHP?

  - by KingNestor

  I'm used to working in ASP.NET / ASP.NET MVC and now for class I have to make a PHP website. What is the equivalent to Master Views from ASP.NET in the PHP world? Ideally I would like to be able to define a page layout with something like: Master.php <html> <head> <title>My WebSite</title> <?php headcontent?> </head> <body> <?php bodycontent?> </body> </html> and then have my other PHP pages inherit from Master, so I can insert into those predefined places. Is this possible in PHP? Right now I have the top half of my page defined as "Header.html" and the bottom half is "footer.html" and I include_once both of them on each page I create. However, this isn't ideal for when I want to be able to insert into multiple places on my master page such as being able to insert content into the head. Can someone skilled in PHP point me in the right direction?

• Apply a specific class to the first item in a series with PHP

  - by Thomas

  I have a php script that echoes a series of uploaded images and I need to apply a class to the first image echoed in the series. Is this possible? For example, if I want to display 10 images and apply a class to only the first image, how would I go about it? Here is the code, I am working with: <div id="gallery"> <?php query_posts('cat=7'); while(have_posts()) { the_post(); $image_tag = wp_get_post_image('return_html=true'); $resized_img = getphpthumburl($image_tag,'h=387&w=587&zc=1'); $url = get_permalink(); $Price ='Price'; $Location = 'Location'; $title = $post->post_title; echo "<a href='$url'><img src='$resized_img' width='587' height='387' "; echo "rel=\"<div class='gallery_title'><h2>"; echo $title; echo "</h2></div>"; echo "<div class='pre_box'>Rate:</div><div class='entry'>\$"; echo get_post_meta($post->ID, $Price, true); echo "</div><div class='pre_box'>Location:</div><div class='entry'>"; echo get_post_meta($post->ID, $Location, true); echo "</div>\""; echo "'/></a>"; echo ""; } ?> On line 13, the code looks like this: echo "<a href='$url'><img src='$resized_img' width='587' height='387' "; For the first item only, I need it to look like this: echo "<a href='$url' class='show'><img src='$resized_img' width='587' height='387' ";

• PHP Commercial Project Function define

  - by Shiro

  Currently I am working with a commercial project with PHP. I think this question not really apply to PHP for all programming language, just want to discuss how your guys solve it. I work in MVC framework (CodeIgniter). all the database transaction code in model class. Previously, I seperate different search criteria with different function name. Just an example function get_student_detail_by_ID($id){} function get_student_detail_by_name($name){} as you can see the function actually can merge to one, just add a parameter for it. But something you are rushing with project, you won't look back previously got what similar function just make some changes can meet the goal. In this case, we found that there is a lot function there and hard to maintenance. Recently, we try to group the entity to one ultimate search something like this function get_ResList($is_row_count=FALSE, $record_start=0, $arr_search_criteria='', $paging_limit=20, $orderby='name', $sortdir='ASC') we try to make this function to fit all the searching criteria. However, our system getting bigger and bigger, the search criteria not more 1-2 tables. It require join with other table with different purpose. What we had done is using IF ELSE, if(bla bla bla) { $sql_join = JOIN_SOME_TABLE; $sql_where = CONDITION; } at the end, we found that very hard to maintance the function. it is very hard to debug as well. I would like to ask your opinion, what is the commercial solution they solve this kind of issue, how to define a function and how to revise it. I think this is link project management skill. Hope you willing to share with us. Thanks.

• PHP package manager

  - by Mathias

  Hey, does anyone know a package manager library for PHP (as e.g. apt or yum for linux distros) apart from PEAR? I'm working on a system which should include a package management system for module management. I managed to get a working solution using PEAR, but using the PEAR client for anything else than managing a PEAR installation is not really the optimal solution as it's not designed for that. I would have to modify/extend it (e.g. to implement actions on installation/upgrade or to move PEAR specific files like lockfiles away from the system root) and especially the CLI client code is quite messy and PHP4. So maybe someone has some suggestions for an alternative PEAR client library which is easy to use and extend (the server side has some nice implementations like Pirum and pearhub) for completely different package management systems written in PHP (ideally including dependency tracking and different channels) for some general ideas how to implement such a PM system (yes, I'm still tinkering with the idea of implementing such a system from scratch) I know that big systems like Magento and symfony use PEAR for their PM. Magento uses a hacked version of the original PEAR client (which I'd like to avoid), symfony's implementation seems quite integrated with the framework, but would be a good starting point to at least write the client from scratch. Anyway, if anybody has suggestions: please :)
