What are the potential pitfalls of not setting the correct values for upload_max_filesize, post_max_size, and max_lifetime in PHP?

If the values for upload_max_filesize, post_max_size, and max_lifetime are not set correctly in PHP, it can lead to issues such as users being unable to upload large files, data being truncated during POST requests, and sessions expiring prematurely. To solve this issue, you need to adjust these values in the php.ini configuration file to accommodate the needs of your application. 

// Set the correct values for upload_max_filesize, post_max_size, and max_lifetime in php.ini

// Example values
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');
ini_set('session.gc_maxlifetime', 3600);
