PHP - Anonymous Function

Question

Why doesn't this work:

echo (function() {
    if (strlen($_POST["a"]) > 150) {
        return "123";
    }

    return "abc";
})();

is there anyway to do this in PHP?

Like in JS you can do:

var x = (function() {return "asd";})();

Maybe your looking for something like this: http://php.net/manual/en/functions.anonymous.php — Rizier123, Nov 29 '14 at 11:17
Why would you be able to do it in php just because you can do it in js? They're different languages — Clive, Nov 29 '14 at 11:18
@Clive It's not an unreasonable question to ask if similar functionality exists... — lonesomeday, Nov 29 '14 at 11:19
evet it would be js, you still have parentheses mistake on "echo" — Adem, Nov 29 '14 at 11:20
@lonesomeday I was addressing the first part of the question, "Why doesn't this work". — Clive, Nov 29 '14 at 11:20
@Adem Just to make it look better, not because idk that "echo" is not a function — , Nov 29 '14 at 11:23
I meant, it should be echo(function(){...}()); btw, @lonesomeday's answer is pretty good — Adem, Nov 29 '14 at 11:24

You can do this, just not with the elegant syntax of Javascript. You need call_user_func:

echo call_user_func(function() {
    if (strlen($_POST["a"]) > 150) {
        return "123";
    }

    return "abc";
});
