return x[1];

function f(x) {
    return x[1];
}

It cannot translate it.

But it can translate

function f(x) {
    return x[0];
}

[zaoqi]

and

function f(x) {
    return x[1+0];
}

[zaoqi]

function f(x) {
    return x[1+1];
}

and so on

[garata]

function f(x) { return x[+1]; }

The + operator triggers numeric conversion in this case. Does js2php support JS types coercion?

Very interesting issue anyway.
