\s php code example

Example 1:

<?php
echo "Hello world";

// ... more code

echo "Last statement";

// the script ends here with no PHP closing tag

Example 2: 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'];
}
