Question

I’m trying to log into a forum using cURL and save the cookie to a file, then parse the cookie to get the phpbb2mysql_sid cookie. Here’s my code thus far:

<?php

$curl = curl_init();

$cookieFile = 'C:\xampp\htdocs\cookies\\' . uniqid(true);

// Login
curl_setopt($curl, CURLOPT_URL, 'http://localhost/phpbb2/login.php');
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookieFile);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_POST, true);
$postVars = array('username' => 'username', 'password' => 'testing', 'autologin' => 'on', 'login' => 'Log in');
curl_setopt($curl, CURLOPT_POSTFIELDS, $postVars);
$resp = curl_exec($curl);

// Parse sid from cookie file
preg_match('/phpbb2mysql_sid\t(.*)/', file_get_contents($cookieFile), $match);
$sId = $match[1];

echo $sId;

However, I’m getting this error when I run the script:

Warning: file_get_contents(C:\xampp\htdocs\cookies\150367764c4ef3) [function.file-get-contents]: failed to open stream: No such file or directory in C:\xampp\htdocs\leech\post.php on line 18

Notice: Undefined offset: 1 in C:\xampp\htdocs\post.php on line 19

If I check my filesystem the file is there. And the code to get the file contents is after the cURL request, so the file should exist, right?

Answer 1

Found the problem. The cookie file is only saved once curl_close() is called. Simply close the cURL handle before the file_get_contents() call and it works like a charm.
