Script stoping with no error when parsing a mail attachment of 3 MB

I am having troubles with a email parser when a attachment larger than 2MB is being encoded in base64.

The encoder I am using is called mime_parser.php made开发者_如何学JAVA by Manuel Lemos http://www.phpclasses.org/package/3169-PHP-Decode-MIME-e-mail-messages.html

This is the part of my code where the script just stops and prints only half of var_dump, it's like the script timed out:

$parameters2=array('File'=>$message_file,'SaveBody'=>'tmp/','SkipBody'=>1);
                echo "<div style='display: none;'>";
                $success2 = $mime->Decode($parameters2, $decoded2);             
                echo "</div>";

                $mime->Analyze($decoded2[0], $results);

I also added this lines at the top of the code to ensure that there is no time limit or memory limit and I am positive that there is no safe_mode on on the server

set_time_limit(0);
ini_set("memory_limit","1024M");
error_reporting(-1);

Also no errors/notice/warnings are reported. Anyone has any idea on what to check to make this work ?

You need to ensure that "upload_max_filesize" is set large enough in your php.ini file to support the filesizes you are attempting to attach.
