How to allow downloading a file of 1GB
<p>I want to allow the user to download a file up to 1GB in size, but according to my code only a file of 113MB can be downloaded...</p>

<pre><code>header('Content-type: application/zip');

//open/save dialog box
header('Content-Disposition: attachment; filename="check.zip"');

//read from server and write to buffer
readfile('check.zip');
</code></pre>

<p>Can anyone tell me how to download a larger file?</p>
