Question

I\'m trying to reduce the warnings that are sent to my apache server log.

Call-time pass-by-reference has bee

Answer 1

You could pass in the array, let it manipulate it, and then "return" it, instead of messing with the original reference. It shouldn't be too hard to just include a return and assignment.

public function takeScriptsWithMarker($lines, $marker) {
    //...
    return $lines;
}

Usage:

$lines = takeScriptsWithMarker($lines, $marker);
