We've been having lots of problems with references (especially storing references to
objects in arrays). We beleive we've narrowed a big part of our problems down to the
following example.
<?php
// What's the difference between this...
function foo(&$b) {
global $c;
$c = &$b; // I don't want a COPY of the variable I want a REFERENCE
}
$a = "Start";
foo($a);
$c = "End";
echo $a; // Shouldn't this echo "End" not start?
// ... and this ...
$a = "Start";
$b = &$a;
$c = &$b;
$c = "End";
echo $a; // This echoes "End" as is expected
// The latter works just fine but the former doesn't. Why not?
?>
I posted a similar example on the PHP mailing list only to be told PHP doesn't support
C pointers. What a nice piece of advice. Too bad it doesn't apply here.
This introduces all kinds of problems especially when using objects and trying to
create object container classes.
Thanks,
