$lister is not used, you could remove the assignment.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for variable assignements that are either overwritten by other
assignments or where the variable is not used subsequently.


$myVar = 'Value';
$higher = false;

if (rand(1, 6) > 3) {
    $higher = true;
} else {
    $higher = false;
}





Both the $myVar assignment in line 1 and the $higher assignment in line 2
are dead. The first because $myVar is never used and the second because
$higher is always overwritten for every possible time line.
