        case 1: 1;
        case 0: 1;
        case _<0: throw new Exception("Less than 0 is not allowed, " . _ . " provided");
        case _: fibo(_ - 1) + fibo(_ - 2);

}

patterns.php

<?php

$people = [
    ["name" => "foo", "age" => 25],
    new User("bar", 33),
    ["user" => new User("baz", 31)],
];

function getAge($user) {
    return match($user) {
        case ["age" => _]: _;
        case User: $user->getAge();
        case ["user" => _]: _->getAge();
    }
}

getAge($people[0]); // 25
getAge($people[1]); // 33
getAge($people[2]); // 31

I mentioned $_ because then you could reuse the existing functionality to embed the place holders into double quoted strings.

which IMHO is very useful for conciseness.

Sure, I was just demonstrating the concept. The exact syntax is definitely up for grabs.

Honestly I really didnt think it would look that good in php. Looks a bit better then scala even.

Hi,

I was looking at your examples, which PHP version are you using? I cannot find any documentation about the match() statement, not even in the RFCs.
