Is it possible to declare multiple arrays in PHP in one line?

$userAnswers  = array();
$questionIDs = array ();
$sqlAnswers = array();
$sqlAnswersQuery = array();
$correctAnswers = array();

Any cleaner ways of doing this?

NOTE: The contents of these arrays are all DIFFERENT. I don't think setting them equal to each other would work.

There is a way. Wether you like it or not is another question:

$userAnswers = $questionIDs = $sqlAnswers = $sqlAnswersQuery = $correctAnswers = array();

I'm not a fan of this. This isn't easy to read, especially for the-new-guy-who-doesn't-know-this-code. This works for small amounts of variables, but even then with caution:

$hasErrors = $hasWarnings = false;

I think the way you should declare the variables as array depends on how you set the first values, we can't see enough code to answer based on that.

All of my arrays are going to have different contents, would setting them equal to each other make them have all the same contents? –  Nicholas Roberts Jun 22 at 7:44

Nope, it's not by reference, you just all set them to the last value of the line. But again, your current method is a better plan. Just add a few spaces to line up the equation signs, will be enough. –  Martijn Jun 22 at 8:19
    
Cool, thanks man. –  Nicholas Roberts Jun 22 at 16:24

This is good as it is. It's recommended to have one statement per line, for better readability: code is easier to read when the logic flows from top to bottom, with no distractions sideways. So even if there was a way to do this on one line, you really shouldn't.
