The assignment to $key_size is unused. Consider omitting it like so list($first,,$third).
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This checks looks for assignemnts to variables using the list(...)
function, where not all assigned variables are subsequently used.


Consider the following code example.


<?php

function returnThreeValues() {
    return array('a', 'b', 'c');
}

list($a, $b, $c) = returnThreeValues();

print $a . " - " . $c;





Only the variables $a and $c are used. There was no need to assign $b.


Instead, the list call could have been.


list($a,, $c) = returnThreeValues();
