My problem is illistrated by the following test code:
class test {
var $flag = 0;
function getFlag() { return $this->flag; }
var $t;
function Init() {
$c = new test;
$this->t = $c;
$c->flag = 1000;
}
function EchoFunc() { echo("=" . $this->t->getFlag()); }
}
$test = new test;
$test->Init();
$test->EchoFunc();
When run, the number 0 is returned. Given copying symantecs, this is what
you would expect. $c is initilized with flag=0, the next line takes a copy
of $c and puts it in $t, the next line sets flag=1000 on $c, but not on $t.
However I would like refernce semantics and the final output of this script
to be 1000. So I changed the line to "$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?
Thanks,
James.
