Firstly, you need to pass in the $greeting variable for it to be in the functions scope - see the PHP manual for variable scope. It is best avoid using globals as they are harder to debug and test.

Secondly, you have missed out the assignment for the $greeting variable.

Thirdly, you have forgotten to return the value from the function so it can be echod out. See the PHP manual for functions.

Fourth, $2nd is not a valid variable name. Variables must start with a letter. See the relevant manual page.

$greeting = 'Hello';

function frank ($greeting) {
    $return = '';
    $name = 'frank';
    $second = 'robson';
    $return .= $greeting;
    $return .= $name;
    $return .= $second;
    return $return;
}

echo frank($greeting);
