    - by user632027
    Following code: <?php $test_array = array(); $test_array['string_index'] = "data in string index"; $test_array[] = "data in index 0"; $test_array[] = "data in index 1"; $test_array[] = "data in index 2"; foreach($test_array as $key => $val) { if($key != 'string_index') { echo $val."<br>"; } } ?> gives result: data in index 1 data in index 2 Question is - where is "data in index 0"??? How to get elements from numeric indices 0-n? Also if I change 'string_index' to something else which doesn't exist, it echoes everything except [0]. Plz, explain me this. Thnx in advance

  • Using php to create a password system with chinese characters

    - by WillDonohoe
    Hi guys, I'm having an issue with validating chinese characters against other chinese characters, for example I'm creating a simple password script which gets data from a database, and gets the user input through get. The issue I'm having is for some reason, even though the characters look exactly the same when you echo them out, my if statement still thinks they are different. I have tried using the htmlentities() function to encode the characters, the password from the database encodes nicely, giving me a working '& #35441;' (I've put a space in it to stop it from converting to a chinese character!). The other user input value gives me a load of funny characters. The only thing which I believe must be breaking it, is it encodes in a different way and therefore the php thinks it's 2 completely different strings. Does anybody have any ideas? Thanks in advance, Will

  • Disabled Select drop down checking through PHP

    - by user541597
    I have a couple of drop down boxes I access through POST with PHP. When the boxes are disabled and not equal to zero I have the program do something. However when they are disabled I do not want them to do anything. The way I check if the boxes are active is by using an if statement if ($_POST['box'] != "blank"){ //do something } So basically I check if the box is not in the default blank position run the if statement. However when it is disabled I am not sure how to check or what kind of value it returns if any. What can I add to the if statement so it will not go into the loop when the boxes are disabled? I tried: if ($_POST['box'] != "blank" || $_POST['box'] != ""){ //do something } But that did not work. Any ideas?

  • PHP __call vs method_exists

    - by neo
    The Project I'm working on contains something like a wrapper for call_user_func(_array) which does some checks before execution. One of those checks is method_exists (In Case the supplied first argument is an instance of a class and the second is a method name) The other is_callable. The function will throw an exception if one of those checks fails. My Code contains an array with function names (setFoo, setBar, etc.) and the php magic function for overloading (__call) which handles setting, replacing and deletion of certain variables (better certain array elements). The Problem: method_exists will return false if the function is not defined. Do I have any chance to get a true if the __call function does proper handling of the request?

  • session expires to soon in php

    - by user1669425
    I want to extend a session time so that a session variable does not expire until after 12 hours. Problem is that after 24 minutes (default time for a session until it expires) of inactivity it still expires the session and hence gives me undefined indexes for those SESSION variables. What else do I need to do in the code below in order to be able to extend the sessions so that it does not expire on its own until 12 hours has passed: <?php ini_set('session.gc_maxlifetime',12*60*60); ini_set('session.cookie_lifetime',12*60*60); phpinfo(); session_start(); ....//rest of code below ?> in phpinfo() it states this below for gc_maxlifetime: Local Value Master Value session.gc_maxlifetime 43200 1440 session.cookie_lifetime 43200 0

  • Both sql LAST_INSERT_ID() and PHP insert_id return 0

    - by jakubplus
    I've been searching google a lot for this issue and really found nothing. People just keep copying MySQL documentation on last_insert_id and nothing else. I've got an issue regarding last_insert_id, because for both situations (php & sql) it returns 0. YES: I've set a PRIMARY & UNIQUE field with AUTO_INCREMENT value YES: i've done some inserting before NO: Making double query with INSERT AND SELECT LAST... doesn't work. I've created a class Db for maintaining connection & query: class Db { public function connect() { $db = new mysqli('','','','',''); ... return $db; } public function insert() { $this->connect()->query("INSERT INTO bla bla..."); return $this->connect()->insert_id; } } And it doesn't work.

  • PHP Case Insensitive Word Replacement

    - by zuk1
    Ok I'm trying to make search terms bold in this search script I'm making, except I can't get it to work case insensitive. function highlight($term,$target){ $terms = explode(" ", $term); foreach($terms as $term){ $result = (eregi_replace($term, "<strong>$term</strong>", $target)); } return $result; } That is the function I have so far.. It says on PHP.net that eregi_replace is case insensitive matching but it's obviously not working for some reason. (I'm a noob). Any ideas? :D

  • MySQL Access in Php to a database created in C-Panel

    - by Rhys Drury
    Basically, i'm having trouble connecting to a mysql database using a php web page. I created the database in C-panel using the wizard i'm connecting like this $db_host = "localhost"; //your host Database address $db_username = "xxxx"; //your account username $db_pass = "xxxxx"; //your account password $db_name = "xxxxx"; //your database name @mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); @mysql_select_db("$db_name") or die ("no database"); But all my page seems to do is trigger the " could not connect to mysql" my page does have wordpress installed at the minute but I'm planning to get rid of it as I'm creating my site myself. I'm just baffled why it can't connect, because in Phpmyadmin ( a feature on C-panel) it says the database is in localhost.

  • Beginners PHP / mySQL question

    - by Reg H
    I'm brand new to PHP & MySQL, and one function I'm creating needs to access a large table or database. I've created the database and it's currently in a MySQL table, which I'm accessing with no problem. The table is 11,000 rows in length, with 8 columns (all text less than 8 characters long) - it's static, and will never change. Without getting too particular, my users will hit a button which will trigger scripts to access the data, say 500 times or more. So in general would it be better practice to include all of this data in a big 'switch' or 'if... then' conditional right in my scripts, rather than opening and accessing the database connection hundreds, or maybe even thousands of times? It just seems like that might be a bottleneck waiting to happen. Thanks!

  • php vs python django or something else for CMS module

    - by Michael
    We're looking to develop a CMS module for our website and I need some help in choosing the language/framework for this project. Basically we need to develop a "help' module like this one from ebay http://pages.ebay.com/help/index.html which will contain a lot of static pages with nice URLs for SEO. The application must run fast using low computer resources. We have been looking to use php on a custom made mvc framework but we received advice from other sources that py/django is the exactly language/framework that we need in terms of maintainability and development speed because it was developed for exactly this kind of projects so I need an expert advice on this matter with pro and cons for each choice.

  • PHP detect if page is reloaded with PHP_SELF

    - by FFish
    I have a form that reloads the page with the updated data: <form name="form" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> ... <input type="submit" name="Submit" value="Update data"> </form> When the page is updated I want to display a message "Data updated". There was something like this with Referer I beleve, but can't remember. btw I am also using: if (isset($_POST['Submit'])) { // prevent resending data header("Location: " . $_SERVER['PHP_SELF']); } to avoid the annoying resending data message when the user clicks the back button. Is this correct?

  • Problems deleting cookies, won't unset (PHP).

    - by RemiX
    I've tried searching the php manual and internet on how to delete cookies and I've tried it the exact same way they all say: setcookie("name", '', 1); or setcookie("name", '', time()-3600); But when I check the cookies in the cookies dialog in Firefox, it's still there with the same value. I set this cookie using the following line: setcookie("name", $value, time() + 259200, $path); I found this question on stackoverflow: http://stackoverflow.com/questions/2497501/cookie-wont-unset, but none of the answers solved the problem. I also tried putting all paramaters in, like the author said, but it had no effect. Does anyone see the problem?

  • Bible reference books (PHP / MySQL / Unix)

    - by Josh K
    I'm looking for some nice heavy books to liter around my desk and make it look like I'm a hard core programmer. On the occasion that I might want to look something up they will also need to be useful dependable books. I'm looking for the equivalent bible in PHP, MySQL, and Unix. Should be laid out with some chapters I can actually read, along with having an in-depth reference to that particular subject. I know that the majority of this can be found on Google, but I would prefer it in book form.

    - by chance
    Hey SO, I have a question, pretty new at PHP and MySql but was curious is it possible to display only the most recent column to a table, from a database? I know it is possible to display a list of all information, or if you have just one column of information in your table to display that using the Here is my code for my basic script (just loads 1 column of information) I would like it to only print out the recent column i added to the table $con = mysql_connect ("localhost","username","password"); if (!$con) { die ('Could not connect:' . mysql_error()0; } mysql_select_db("db_name", $con); $result = mysql_query(Select column FROM table"); while($row = mysql_fetch_array($result)) { echo $row['column']; } mysql_close($con); * keep in mind, im not looking for someone to shoot me my code with it completed, though it would be handy, however just giving me the options of what I have to do, or what the script is called would be plentiful enough for my research, thanks!

  • Passing Large amount of data in PHP.

    - by Simple
    I would like to know what is the best way to pass a large amount of XML data from one PHP script to another. I have a script that reads in an XML feed of jobs. I would like to have the script display a list of the job titles as links. When the user clicks a link they would be taken to another page displaying the details for that job. The job details are too large to send in the query string, and it seems poor style to start a session for data that isn't specific to that user. Any ideas?

  • PHP Framework Benefits / Downfalls

    - by Lizard
    I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can definitely see the benefits of MVC keeping the logic separate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

  • Best use of Jquery sliders and PHP

    - by Coronier
    Hello there, I have two questions: What's the best way to send sliders' values to a PHP page ? I'm associating each slider (several per page) with an hidden form so far, but I wonder if there's a "cleaner" way to do this. Related to the 1st question; I've some trouble with the script: var score = $(this).slider( "option", "value" ); $(this).closest("input[type=='hidden']").val(score); It doesn't set the value of the hidden input. Can somebody tells me what's wrong ? Thanks
