phpinfo and detecting upload max filesize

One of the easiest scripts to write is:

<? phpinfo(); ?>

which displays a long colorful page all about your server configurations. Look here to see what extensions are enabled, or would need to be recompiled with them enabled - if you wanted to use an extension. There are 2 pieces of info I often go looking for, to see how large of file upload can be allowed. PHP has a "glitch" in that if your filesize exceeds the server's limitation the value of $_FILES['userfile']['size'] is again 0. And to top it off, the user most likely waited a minute for this to occur. So I think its a good idea to tell the user about the restriction with a simple:

echo "(Limit: ".fetch_upload_limit()." )";

<?
function fetch_upload_limit()
{
 if(ini_get('post_max_size') < ini_get('upload_max_filesize')) 
 { 
     return ini_get('post_max_size');
 } 
 else 
 { 
     return ini_get('upload_max_filesize'); 
 }
} // Usage: echo fetch_upload_limit();  Displays: 2M
?>
