Include this line in an .htaccess file in the same directory as the script:
php_value upload_max_filesize 128M
The above line will modify the upload_max_filesize to 128MB for all scripts in the same directory as the .htaccess file. Replace the number 128 with an appropriate megabyte value that your script requires. The default upload_max_filesize value on our servers is set to 32MB, and a successful modification of the upload_max_filesize limit will show in your PHP info file.
