When uploading a very large file in PHP, how much RAM is required on the server?
<p>I read  <a href="http://www.php.net/manual/en/ini.core.php#ini.post-max-size" rel="nofollow">http://www.php.net/manual/en/ini.core.php#ini.post-max-size</a>.</p>

<p>memory_limit must > post_max_size . Then if  user upload a file 500MB then how much total RAM use ?</p>

<p>does it use >500MB ?</p>
