PHP Fatal error: Cannot use $this as parameter

Question

I\'ve the following PHP method which is part of the codebase which was working fine:

Answer 1

Just skip $this argument, change

function ($this) {
    return $this;
}

to

function () {
    return $this;
}

Look at Example #5 Automatic binding of $this on Anonymous functions page:

testing();
$function();
?>
