?? has lower precedence than &&, so this is true ?? (false && 0 > 0). See https://www.php.net/manual/en/language.operators.precedence.php for operator precedence in PHP.

Description:
------------
Using the null coalesce operator inside an if paranthesis using and resulting in false will match the condition anyway when the returned value is true.

Test script:
---------------
if (true ?? false && 0 > 0) {
    echo 'Should not be true';
}
