I'm trying to do some extension programming, and I'm pretty confused
by the whole zval thing. In particular, references are a little
mysterious. If I have
$foo = "zonk";
$bar =& $foo;
in PHP, what actually happens? Specifically, if I wanted a function
that did such a reference assignment:
$foo = "zonk";
$bar = "baz";
ref_assign($bar, $foo); // $bar =& $foo;
what has to happen in ref_assign?
Thanks,
Tim
