If you are using a PHP script and want to increase the "post size" or the "size of a file I can upload", then you want to adjust your settings in php.ini.
- Locate your php.ini file. If you do not have one or know where to look, please read the related article to learn more about php.ini.
- Edit that file and locate the "upload_max_filesize" and "post_max_size" settings.
- The values to the right of the = (equal sign) need to be increased.
- Save and enjoy.
