Is there a way to upload a picture from a remote url to my server using curl? Basically I had a firefox extension that allowed me to right click on a picture and upload it to my server, but now they turned "allow_url_fopen" off and doesn't work. (Just need to know if there's a way, not the actual way) Thanks.

You mean use CURL to fetch an image? Sure, that's what it's for, to fetch things from the Internet.

Another complete coding-newbie question here: How do you replace php's copy() with curl? I've got a wordpress script that uses the copy function to download a file to my website, and allow_url_fopen or something is recently been disabled by my host so it doesn't work anymore. This is the relevant piece of code (I think): code:

Hey guys, I'm helping my GF write her honours thesis with a simple php scraper of a vBulletin board (not SA). I'm not particularly proficient with php and an just making the very first steps. What I need help with is how to get php to "log in" so it can view content available to members. Is there a way to load cookies into php before using file_get_contents($url)?

Amethyst posted:Hey guys, I'm helping my GF write her honours thesis with a simple php scraper of a vBulletin board (not SA). Use cURL - With cURL you can login and let it manage the cookies for you. I don't have a complete example, but this should give you enough idea and get you started: http://coderscult.com/php/php-curl/2008/05/20/php-curl-cookies-example/ Ninja Edit: Is there any reason your using file_get_contents() vs cURL anyway? In 99% of instances I would recommend people use cURL as their first step as it isnt hamstrung by safe mode or url open stuff, and it is far more flexible then other options.

Yarp - No problem Sorry if my last comment seemed abrasive - Among the many things that "irk" me about PHP, things like file_get_contents and copy via remote URL open bother me most since they tend to have issues and are subject to safe mode and other oddball restrictions.

The only reason I'm using it is cause the old site was built with it and its the only way i know how to use: <!-- include file --> I use this for the header and footer so I dont have to change them out on each page. Theres probably a better way to do this right?

And what I failed to mention is that the code I showed is already in one of those 'function' brackets. I'm guessing by the error it gives me you can't put one of those inside another? Here's the complete code thingie excerpt btw. The code I showed previously was just the one in the 'else': php:<?

global $wpdb;
$id = intval($id);
$query = "select id,swf_url,blog_url,blog_id from ".$wpdb->prefix."mochi where id = $id";

$unlink = unlink($game[blog_url]);

}?>Sorry for probably being an idiot, but this is all chinese for me (I'm not chinese). It's all a bit above my head, so I'll probably just have to give up for now and first try and learn basic php.

I have a class with a bunch of methods, and comments in front of each method. Is there a way to grab all those comments in a array or something so I can echo them in an API page? <edit> Just had a friend tell me, use ReflectionClass which is working great. nevermind.

How would I go about making sure something happens 75% or n% of the time? If that didn't make sense, how can I make a random event happen n% of the time whenever a page is loaded. I tried this but this doesn't seem right. php:<? $r = rand(1,100); if($r <= 75) echo "hit"; else echo "miss";?>

for ($i=0;$i<10000;$i++) {
$r = rand(1,100);

I will google PHPDoc and see what it's all about. PHPDoc is perfect for that - not only is it useful when reading the source itself, but it generates an HTML (or whatever else) "help file" that sort of documents your code as per what it can find itself and what you've written.

It's been a long time since I last wrote session scripts and user authorization, so I want to check what I'm doing isn't pointless. I've used the PHP Security Consortium example of sessions to write a three-tiered validation (session active > session user agent (hashed) > url user agent (hashed)). If I set a boolean to true if the validation passes, can I stick an if outside of the session code to call user functions? I.e. if($uservalid == true) { echo userInput(); } Does that destroy the point of checking the session in the first place? My second question (if the answer to the first is positive), can I abstract the session validation to a separate file and just call it like I would any other function? php:<?php session_start(); validate_session(); ?>

Surely if your session is invalid you should most likely kill the script and tell the client to gently caress off, whilst deleting the session? Or just do the latter.

I was thinking of having update forms on certain pages which were only visible to users that are logged in. That way they all existing content is visible. If the session is invalid, the page will still load, but without the form. Is this bad practice?

You can see how this is a problem. What can I do to speed the process up? Are the mail subjects/bodies identical? mail() accepts virtually any number of receivers per call (Example 4, delimit with commas). If each mail has to be tailored to its recipient, you probably have to send them one at a time. The documentation also points to PEAR for bulk sending: http://pear.php.net/package/Mail and http://pear.php.net/package/Mail_Queue.
