The OP requested to assign the return value of func($var) if that return value is true. Otherwise, to hold the original value of $var.

You coughed up this: If $var is true, keep it, otherwise store a return value from func($var).

To put it another way: Specification: if the function returns a true value, store it. Otherwise keep the original value.

Your solution: If the original value is true keep it, otherwise call the function and keep its return value instead.

Inverted logic. But you're not alone; several people upvoted your post, so it must be an easy mistake to make.
