# Form Processing
Form processing in PHP involves reading submitted input from `$_GET` or `$_POST`, validating and sanitizing the values, and then performing an action such as saving to a database or sending an email. The Post/Redirect/Get (PRG) pattern is commonly used to prevent duplicate form submissions on page reload.
