that's right but in what a PHP string actually differs from a JS string? I
mean, in PHP strings are not objects but primitives, but how are they
internally handled?
I'm not sure they're not garbage collected as, say, arrays; in fact strings
are always array of chars, and arrays are usually passed by reference (in
PHP4 only arrays of arrays do, but there's always copy-on-write).
Of course, I'm not sure, that's why I asked
