[SOLVED] Cannot delete cURL Cookie File since upgrade to PHP 8.2

Issue

The following script (stripped down for clarity and simplicity) has run fine for years, but since upgrading from php 5 to 8, the cookie file created is no longer deleted by the unlink command, despite it reporting success, leading to a build-up of these cookie files.

If I take out the CURLOPT_COOKIEJAR line, then the file is deleted just fine.

<?php
    $my_cookie=tempnam("./","XX");
    
    $ch = curl_init();
    curl_setopt ($ch, CURLOPT_COOKIEJAR, $my_cookie);
    curl_close($ch);    
    
    if (unlink($my_cookie)) {    
        echo "success - $my_cookie unlinked<BR>";
    } else {
        echo "fail";    
    }
?>

Any ideas?

Solution

curl_close($ch); does nothing in PHP >= 8.0.0, so the cookie file doesn't actually exist (yet) when you're trying to delete it.

Replace curl_close($ch); with unset($ch);. This will write the cookie file.

See documentation of curl_close:

Note: This function has no effect. Prior to PHP 8.0.0, this function was used to close the resource.
