    copied!<p>This has been bugging me for literally hours already.</p> <p>I can't seem to figure out why PHP <strong>cURL won't download data to a file</strong>. (CURLOPT_FILE is set to a local file.) I am not getting any data. I periodically check the file size of the destination file and it is always zero. To give you a background, I am downloading a 90kb jpeg file (for testing purposes).</p> <p>This is working on my local computer (XP) but not in the website I am working on (Windows Server 2003).</p> <p>I did several tests which made the scenario even weirder.</p> <ol> <li><p><strong>I disabled CURLOPT_FILE to print the data returned by curl into standard output, and the binary data printed</strong>.</p></li> <li><p>Having experienced blocked websites before (since the server implements access control), I tried accessing the file from internet explorer and i was able to see it.</p></li> <li><p>Having experienced blocked downloads before, I tried downloading the file from internet explorer and it was downloaded.</p></li> <li><p>The file is created by fopen('', 'w') but the size remains 0. Despite this successful file creation, I thought maybe PHP has a problem with filesystem write privileges, I set the exe to be run even by non-admin users. Still no download.</p></li> </ol> <p>Has this ever occured to anybody?</p> <p>Any pointers will be appreciated. I am really stuck.</p> <p>Thank you.</p> <p>Here's the curl options I set:</p> <pre><code>$connection = curl_init($src); // If these are not set, curl_exec outputs data. // If these are set, curl_exec does not send any data to the file // pointed to by $file_handler. $file_handler is not null // because it is opened as write (non-existing file is created) curl_setopt($connection, CURLOPT_RETURNTRANSFER, true); curl_setopt( $connection, CURLOPT_FILE, $file_handler ); </code></pre> <p>PS: I'm doing these tests using the command line and not the browser.</p>
