However I would like refernce semantics and the final output of this script
to be 1000. So I changed the line to "$this->t &= $c;" and suddenly I get
the error: "Fatal error: Call to a member function on a non-object in
/user/sh/jmb/Project/Wiki/Public_html/test.php on line 25"
Anyone have any help on what is happening?
$this->t = &$c;
I dunno where &= comes from. I see people using it many times,
but =& makes more sense imo. The & is 'by reference', and putting
it explicitly in front of which variable is to be passed by
reference *seems* more logical to me. Otherwise you could
end up with
$this->t &= $c.$d;
What's being passed by reference at that point?
