Description:
------------
error_reporting(0); does not suppress E_WARNING during a file upload if it exceeds upload_max_filesize (php.ini directive) or MAX_FILE_SIZE (hidden field).

Reproduce code:
---------------
<?php
error_reporting(0);
?>

<form method="post" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="1000" />
<input type="submit" />
</form>

Expected result:
----------------
This should not throw an E_WARNING if you submit the form with a file that exceeds 1000 bytes since error_reporting(0); was set above any code.

Actual result:
--------------
PHP throws a warning message:

Warning: MAX_FILE_SIZE of 1000 bytes exceeded - file...


* This is also true if you submitted a file larger than upload_max_filesize. PHP will throw a warning message:

Warning: upload_max_filesize of 1048576 bytes exceeded - file... (where 1048576 bytes is the php.ini upload_max_filesize directive of 1M in this example)
