  • How to work with PHP abstract?

    - by YumYumYum
    Why would you use such abstract? Does it speed up work or what exactly its for? // file1.php abstract class Search_Adapter_Abstract { private $ch = null; abstract private function __construct() { } abstract public funciton __destruct() { curl_close($this->ch); } abstract public function search($searchString,$offset,$count); } // file2.php include("file1.php"); class abc extends Search_Adapter_Abstract { // Will the curl_close now automatically be closed? } What is the reason of extending abstract here? Makes me confused. What can i get from it now?

  • static images aren't caching with php-generated page

    - by scootklein
    Our website was just converted to being generated by mod_rewrite and php scripts. Images aren't caching in browsers when they seemingly should be. All images follow format: <img src="/images/header.png" /> I must avoid the script completely caching because the PHP parser needs to handle each page dynamically on each request; however, the download overhead of the large images is cumbersome on every single page load. I would ideally provide headers for "Cache-Control: no-cache, must-revalidate" and "Expires: some_date_in_the_past" to force revalidation of the PHP script. Why isn't the browser caching static images with consistent href values across all pages?

    - by fredz0003
    I am trying to figure out what is the best way to make this work, I am new to php. I was able to make my script work to find specific data on my htm file with the following script tested on my local server. <?php include ('simple_html_dom.php'); //create DOM from URL or local file $html = file_get_html ('Lotto Texas.htm'); //find td class name currLotWinnum and store in variable winNumbers foreach($html ->find('td.currLotWinnum') as $winNumbers) //print winNumbers echo "<b>The winning numbers are</b><br>"; echo $winNumbers -> innertext .

  • Google Contacts Data API and PHP

    - by pako
    I'm developing a PHP application to retrieve the list of contacts from a GMail account. I'm looking for a solution which would enable the user of my application to provide the login and password to their Gmail account in my application (as opposed to getting redirected to Google) and then automatically do the retrieval. The retrieval process can be run in PHP or JavaScript (which would then feed the list of contacts back to PHP using Ajax). Is it possible to do that? Which JavaScript API should I use for that? Can someone point me at the right chapter in Google Contacts Data API documentation?

  • Potential issue when using memcache session save handler in PHP

    - by Sean
    I have two load balanced web servers, and I'm using the memcache session save handler with the save path pointing to two memcache servers. It's configured with session redundancy set to two (the number of memcache servers). So PHP is writing session data to both memcache servers, and when I take one of the servers down, everything seems to work fine since the session data has been written to both memcache servers. The problem seems to happen when I use the app for a while with only the one memcache server up, and then bring the other one back up. My theory is that the memcache server comes back up, and PHP then starts asking it for session data which isn't there since it was written to the other server while this one was down. Is there any merit to this theory? Should PHP be asking both servers for the session data and maybe there's some other problem?

  • PHP: Mapped Network Drives

    - by Abs
    Hello all, I have mapped a network drive to a computer in my home network. Now I am trying to access it via PHP - I did this quick test: echo opendir('Z:\\'); This gives me: Warning: opendir(Z:\) [function.opendir]: failed to open dir: No error in C:\wamp\www\webs\tester-function.php on line 3 What have I done wrong here? I don't want my users typing in the UNC path so is there a way to get the UNC path for them and maybe that will work when I try to access it? This is possible in Microsoft languages but I am not sure how to get PHP to do this - maybe using a cmd.exe command? Please note, the mapped drive does exist as I can see it and I can access it. It also does not appear to be a permissions problem as I am assuming it would of complained about this IF it could access that drive...right? Thanks all for any help

  • Best practice for error handling in codeigniter / php apps

    - by Industrial
    Hi everyone, We're working with a new codeigniter based application that are cross referencing different PHP functions forwards and backwards from various libraries, models and such. We're running PHP5 on the server and we try to find a good way for managing errors and status reports that arises from the usage of our functions. While using return in functions, the execution is ended, so nothing more can be sent back. Right? What's the best practice to send a status information or error code upon ending execution of actual function? Should we look into using exceptions or any other approach? http://us.php.net/manual/en/language.exceptions.php

  • PHP Store User Data without Sessions

    - by Sev
    Is there anyway to store users data such as userid, email, etc to be accessible from all pages of a website after they have logged in, but without using sessions or cookies? For example: class User { var $userid; var $username; var $email; .. methods.. } after they login at login.php $currentUser = new User($_POST['username']) now, how do I access $currentUser from another page, such as index.php if I shouldn't use sessions or cookies at all? so that I could do the following in index.php: if ($currentUser->userid > -1) { echo "you are logged in as: " . $currentUser->username; } else { echo "click here to login"; } i asked a similar question before, here, but the answers didn't fulfill my needs.

  • Hide header if node body is empty - Drupal php snippet help

    - by Toxid
    Hello! I've made a content type for links, I'm trying to make a link directory. People only have to submit the link, description is voluntary. If no description is entered, I want the header that says "description" to disappear. The description field is the node body. Right now my snippet looks like this <?php if (!empty($node->body)) {?> <div class="field field-type-link field-field-link-archive"> <h3>Description</h3> <?php print $node->content['body']['#value'] ?></div> <?php }?> I expect this to check if node body is not empty, and if it isn't it'll print what's there. The problem is that the Description header is still printed out even if the node body is empty. Can anyone see what's wrong?

  • Accessing a variable passed by jquery using php

    - by celenius
    How does php access a variable passed by JQuery? I have the following code: $.post("getLatLong.php", { latitude: 500000}, function(data){ alert("Data Loaded: " + data); }); but I don't understand how to access this value using php. I've tried $userLat=$_GET["latitude"]; and $userLat=$_GET[latitude]; and then I try to print out the value (to check that it worked) using: echo $userLat; but it does not return anything. I can't figure out how to access what is being passed to it.

  • Stopping and Starting Apache Using PHP (!)

    - by Abs
    Hello all, I have two problems which are related. 1) I have a batch file that contains this: net stop wampapache net start wampapache Which tries to stop and start my wamp server. When I double click the stop.bat file with the above it works successfully. When I try to run that from my PHP script, it stops the server but doesn't start it fully which I am guessing is because Apache is waiting for that PHP process to exit? function php_kill(){ exec('stop.bat', $output = array(), $return); return $return; } 2) Is there a way to restart my webserver (apache) whilst keeping session variables that PHP needs available? Thanks all

  • PHP: form input field names containing square brackets like field[index]

    - by gidireich
    Hi, I've seen lot of code that handle forms, which creates input fields with names containing square brackets. I understand that this is being somehow converted to PHP arrays when a PHP script examines the $_POST variable. My questions about this: What is the mechanism behind? At which point this names that merely contain brackets are converted to arrays? Is this a feature of the HTPP protocol? Of web servers? Of the PHP language? Continuing the previous question, is this a commonly used hack or a normal programming tool? What are (all) the rules of using brackets in input field names? Can multidimensional arrays be created this way? Thanks, Gidi

  • Twitter oauth php problems

    - by Patrick Gates
    I'm writing some backend script for a twitter app and heres how it's going On the app you click a button that sends you to login.php on my server which logs into my database connects to twitter with my consumer key and secret: $to = new TwitterOAuth($consumer_key, $consumer_secret); $tok = $to->getRequestToken(); $request_link = $to->getAuthorizeURL($tok); and then writes the token and secret to the database, sets a session equal to the id in the database of the token and secret and then redirects to the "$request_link" You then go through the process of logging in and such on twitter and it redirects you to callback.php on my server Callback.php consists of logging into the database again, getting the new token and secret, and then writing the new token and secret to the database and then prompts you to go back to the app Then on the app, all I'm trying to do is access the basic credentials$to->get('account/verify_credentials') and it keeps coming back "could not authenticate you" What am I doing wrong??

  • Determining Terminal lines/cols via PHP CLI

    - by eFrane
    I know that it is quite easy to figure out a terminal's size parameters via the stty -a command. When using local CLI PHP scripts, there is no problem at all on grabbing that output via system() or so. But I am trying the same thing via a php script started from an ssh command. Sadly, all that stty ever returns is: stty: standard input: Invalid argument. The calling code is: exec('stty -a | head -n 1', $query); echo $query[0]; So the question is: If I can output to the terminal and read input from it (e.g. can fread() from STDIN and fwrite() to STDOUT in PHP, shouldn't stty also have valid STDIN and STDOUT?

  • PHP exec() hangs, Error 500

    - by MRX_II
    So, my plan is to make small thumbnails of URL's with PHP and IECapt. IECapt works well, a nice command line tool, gets the full sized image of specified URL in 1 to 4 seconds. But my problem is to execute it trough PHP. This is the code I've trying to get working: exec('IECapt.exe ' . escapeshellarg($URL) . ' ' . escapeshellarg($Filename)) $URL is of course the URL, and $filename is a simplified version of the URL. Sometimes I get the IECapt to snap the image(trough PHP), but it takes awfully long (30-60s), and in the end I always get a 500-error, with no error messages to tell me what's wrong. Both variables are fine, they work manually with commandline: IECapt http://google.com Google.png My server set-up is IIS7 and PHP5.2.9, if relevant. (Windows Vista, all on my personal computer, so full access.) Any ideas?

  • php cURL POST how to follow location

    - by One Stuck Pixel
    I am in a bit of a rut with a cURL issue. The post works greate, the data is POSTED just fine and received ok, but the url of the posted page never appears in the browser after the cURL session is executed, for example look at the following code: $ch = curl_init("http://localhost/eterniti/cart-step-1.php"); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, "error=1&em=$em&fname=$fname&lname=$lname&email1=$email1&email2=$email2&code=$code&area=$area&number=$num&mobile=$mobile&address1=$address1&address2=$address2&address3=$address3&suburb=$suburb&postcode=$postcode&country=$country"); curl_exec($ch); curl_close($ch); The post works fine and I am taken to the cart-step-1.php where I can process the posted data, HOWEVER the location in the URL address bar of the browser remains that of the script page, in this case proc_xxxxxx.php Any ideas how to get the URL address to reflect the page I am actually POSTED to? Thanks a mill

  • Securely using exec with PHP to run ffmpeg

    - by Venkat D.
    I would like to run ffmpeg from PHP for video encoding purposes. I was thinking of using the exec or passthru commands. However, I have been warned that enabling these functions is a security risk. In the words of my support staff: The directive 'disable_functions' is used to disable any functions that allow the execution of system commands. This is for more security of the server. These PHP functions can be used to crack the server if not used properly. I'm guessing that if exec is enabled, then someone could (possibly) execute an arbitrary unix command. Does anyone know of a secure way to run ffmpeg from PHP? By the way, I'm on a dedicated server. Thanks ahead of time!

  • PHP include(): File size & performance

    - by Tom
    An inexperienced PHP question: I've got a PHP script file that I need to include on different pages lots of times in lots of places. I have the option of either breaking the included file down into several smaller files and include these on a as-needed basis... OR ... I could just keep it all together in a single PHP file. I'm wondering if there's any performance impact of using a larger vs. smaller file for include() in this context? For example, is there any performance difference between a 200KB file and a 20KB file? Thank you.

  • How to debug PHP with netbeans and Xdebug

    - by Jon Winstanley
    I have recently tried to get going with Netbeans 6.5 after it rated so highly in the IDE review by Smashing magazine. http://www.smashingmagazine.com/2009/02/11/the-big-php-ides-test-why-use-oneand-which-to-choose/ My main reason for switching from Notepad++ is that I'd like to be able to debug my code and set through it. I have followed the instructions about how to install xdebug from both the vendor http://xdebug.org/ and the netbeans web site. http://www.netbeans.org/kb/docs/php/debugging.html#gettingReady but to no avail. How is it done, has anyone else got debugging working in netbeans? (My setup is: Windows XP, Wamp server 2.0, PHP 5, Netbeans 6.5.1)
