Hi all

Is there a way to use PHP to detect the max file size available for file uploads on the server, as apposed to me setting it manually only to find that large uploads get cut off at a certain size?

Eg. I just want to run something like this:

$file_size = get_server_maxfilesize();

Thanks
Mark

you can run phpinfo();
and then find : upload_max_filesize

Yea but i don't want to set it manually in code ...I want my script to be smart enough to be able to detect it depending on what server it's on ...is that possible?

I know you can do:
ini_get( 'upload_max_filesize' )

...but that returns a value like '2M' (meaning 2 Meg) ...I'd need a value returned in full byte form. ie. 2097152

Any ideas?

Cheers,
Mark

<?php
$mfsize = ini_get('upload_max_filesize');

if ($pos = strpos($mfsize, 'M') != '')
{
      $size = substr($mfsize, 0, $pos);
      $fsize = $size * 1024 * 1024;
}
elseif  ($pos = strpos($mfsize, 'K') != '')
{
      $size = substr($mfsize, 0, $pos);
      $fsize = $size * 1024;
}

echo $fsize;
?>
