Why 1 && 2 == 2

Thank god he didn't try php.

    echo 2 && 1; // 1
    echo 1 && 2; // 1
    echo 2 || 1; // 1
    echo 1 || 2; // 1
    echo 2 ?: 1; // 2

In php ?: is javascript's || Unfortunately there is no && that works correctly.

Came here to say this. If you use var_dump you can see it's coercing the result to a bool.

    $ php -r 'var_dump(1 && 2);'
    bool(true)

Exactly, it's not that bizarre. PHP assumes when you're using && you're going to have a boolean outcome.

The odd bit is that casting a boolean to a string[0] with echo coerces the result to (string) "1" for true and (string) "" for false.

Incidentally, this is identical to the result in GNU C.
