What is the issue with exhausted PHP memory when using $_POST?

When dealing with exhausted PHP memory when using $_POST, it usually means that the script is trying to handle a large amount of data that exceeds the memory limit set in the PHP configuration. To solve this issue, you can increase the memory limit in the php.ini file or optimize the code to handle the data more efficiently.

// Increase memory limit in PHP script
ini_set('memory_limit', '256M');
