Question

In Php if I write something like

If ($this->that()){ return $this->that()}

Does it execute $this->that() twice? Or does that parser figure it out and reduce it to 1 call?

Trying to keep code clean if possible, but don’t want to double by execution time for sake of one variable assignment.

Answer 1

Yes, it executes twice.

To make it execute once, you should save it’s value into a variable and return the variable:

if ($value = $this->that()) {
    return $value;
}
