Hello,

your max upload size in set in apache's configuration file httpd.conf. If you don't have access to it you can set those values in a .htaccess file in your script's directory. Then set the following values:

<FilesMatch your_file.php>
php_value post_max_size "50M"
php_value upload_max_filesize "40M"
</FilesMatch>
