Include this line in an .htaccess file in the same directory as the script:
php_value post_max_size 128M
The above line will modify the post_max_size 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 post_max_size value on our servers is set to 32MB, and a successful modification of the post_max_size limit will show in your PHP info file.
