What is php?

PHP stands for Hypertext Preprocessor. 
It is an open source server-side scripting language which is widely used for web development.
It supports many databases like MySQL, Oracle, Sybase, Solid, PostgreSQL, generic ODBC etc.

Php ?:

// Example usage for: Ternary Operator
$action = $_POST['action'] ?: 'default';

// The above is identical to this if/else statement
if (empty($_POST['action'])) {
    $action = 'default';
} else {
    $action = $_POST['action'];
}
