Why doesn't php curl save a cookie in my cookie?

Question

I am trying to save a cookie in curl cookiejar. I simplified my code but didn't work.

<?php $cookie_file = './cookies.txt'; if (! file_exists($cookie_file) || ! is_writable($cookie_file)){ echo 'Cookie file missing or not writable.'; exit; }//cookie_file is writable, so this is not the issue $ch = curl_init (html_entity_decode("http://localhost/kiala_test/setcookie.php")); curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie_file); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HEADER, 1); //curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); $output = curl_exec ($ch); echo $output; ?> 

setcookie.php

 <?php $value = 'something from somewhere'; setcookie("TestCookie", $value); ?>

so testcookie is in the header, but my cookie remains empty. What am I doing wrong? what can i do to make this example work? thanks!

When setting CURLOPT_COOKIEJAR you need to use an absolute path. You can do this easily using:

 curl_setopt ($ch, CURLOPT_COOKIEJAR, realpath($cookie_file) );
