I could see how that could be very handy, some would probably complain about the readability, but I think its a nice little technique if it works for you

Much thanks for your comment and input Paul.

My favorite trick here is using the ternary operator as a fake “gated or”. By that, I mean, the value returned is the second value only if the first is falsy.

$val = ($x = $a) ? $x : $b;

If A is truthy, then $val === $a.
If A is falsy, then $val === $b.

This is handy when getting the results of a function.

$val = ($x = myFunction()) ? $x : anotherFunction();
