What is the difference between these PHP operators?

$str = 'ok';
$chkStr1 = isset($str) ? true : false;  // will output true
$chkStr2 = (isset($str)) ? true : false;  // will output true
$chkStr3 = (isset($str) ? true : false);  // will output true

The result is the same for all three

Why would there be a difference? They're all the same, plus or minus some superfluous parentheses. – Robby Cornelissen Oct 25 '21 at 08:11

No difference, ternary operator : condition executes first and then based on output one or another value assigned to variable – Alive to die - Anant Oct 25 '21 at 08:11

That's like asking the difference for `1 + 1`, `(1) + 1` and `(1 + 1)`. – AymDev Oct 25 '21 at 08:17
parentheses are for setting precedence , but you only have a single ternary operator so if you add more parentheses it will make no difference (for your case) – Ken Lee Oct 25 '21 at 08:33
