How can the size limitation of $_POST data be managed or adjusted on a server?

To manage or adjust the size limitation of $_POST data on a server, you can modify the PHP configuration settings related to post_max_size and upload_max_filesize. These settings can be adjusted in the php.ini file or using the ini_set() function in your PHP script.

// Adjust post_max_size and upload_max_filesize settings
ini_set('post_max_size', '20M');
ini_set('upload_max_filesize', '20M');
