Continue normally because you know its setĪnd like has been said, you can shorthand the ternary and just use: $target_val = $values ?: null īut you will get a notice thrown on array value not set so I always just use isset and assign a value in the ternary to avoid silencing messages for no reason. I know that the value is not set and if I want to check if it is set: if(!!$target_val)Īnd it may be a bit verbose but you can do it all in one swoop like this: if(!($target_val = isset($values) ? $values : null)) in this example if I do: if(!$target_val) HOME HTML5 CSS3 JAVASCRIPT JQUERY BOOTSTRAP5 v4.

I have been struggeling with this for a couple of hours and my head is exploding at this point. $target_val = isset($values) ? $values : null Sorry to open this up again, but I spent a good 20 min testing out cases because this conversation did so many loops through multiple techniques but didn't appear to settle. Best way is always the ternary operators.
