/*

    create_function has been removed in PHP 8 and above...

    You can rewrite the functions as per the example below

    to ensure your code is compatible:

*/

/// Old (using create_function to create anonymous function)

$func = create_function('$x,$y', 'return $x * $y;');

echo $func(4, 5);

​

/// New (using native anonymous function)

$func = function (int $x, int $y) {

    return $x * $y;

};

echo $func(4, 5);
