I'd like to ask if it's possible to print "null" instead of nothingness in php8. Let me explain: 
$player = null;
echo $player;

What it prints:
What I want: null

  • null is a empty string, its like echo ''; – Grumpy Mar 18 '22 at 18:11

Depending on what "nothingness" means to you, you could use one of the following:

echo $player ?? 'null'; // null coalescing operator

// or

echo $player ? $player : 'null'; // ternary operator

// or

echo !empty($player) ? $player : 'null'; // ternary operator with empty() check, which will not throw an error when the $player variable does not exist 

// or

echo $player ?: 'null'; // ternary operator shorthand

  • For `null` specific ternary options that can be added as opposed to conditionally falsey values (`0, "", false`), Use `null === $player ? 'null' : $player` and `isset($player) ? $player : 'null'` – Will B. Mar 18 '22 at 18:55
