it seems a bit odd how the ternary operator works in php, can someone shed light?

$z = 'testval';
$x = 'hello ' . isset($z) ? $z : ' notfound';

var_dump($x);  //testval

this results in the expected result:

$z = 'testval';
$x = 'hello ' . (isset($z) ? $z : ' notfound');

var_dump($x); //returns hello testval

I'd say you're focusing on the wrong operator. The ternary is doing just fine, it's the concatenation operator that is showing a difference – Phil May 18 '18 at 04:46
its about operator precedence. – Jigar Shah May 18 '18 at 04:48

Think of the first example like this ~ `$x = ('hello' . isset($z)) ? $z : ' notfound'` – Phil May 18 '18 at 04:49
