title: File upload maximum size in php
body: <p>I'm implementing a file upload system using cakephp. I'm using php 5.2.5 and cakephp 1.2. Below I have mentioned the maximum file sizes that I have given in php.ini.</p>
  
  <pre><code>post_max_size = 2000M
  upload_max_filesize = 1800M 
  memory_limit = 3328M  
  </code></pre>
  
  <p>But I need to upload 5 GB files and when I change the file upload sizes to 5GB in php.ini web server doesn't respond. 
  Is there any method that I can use to upload 5 GB files to my system? and How can I calculate the maximum size of the file that I can configure in php.ini.</p>
  
  <p>By migrating to php 5.3 will I able to support more capacity for file uploading. </p>
  
  <p>Cheers !!!!</p>
