Hi Brandon:

Yeah, that's a good article. I've seen it on other occasions. But she's
kind of "lying" too...
<?php
// Regular variables' "copy-on-write reference set" Sara discusses:
$a = 'foo';
$b = $a;
$a = 'bar';
echo "\$a = $a, \$b = $b\n";
// While Sara is right about "copy-on-write reference set" being
// the model when changing objects to other data types:
class copy_on_write {
public $m = 'foo';
}
$a = new copy_on_write;
$b = $a;
$a = 'bar';
echo "\$a = $a, \$b->m = $b->m\n";
// Copy-on-write is not what happens when dealing only with objects:
class not_copy_on_write {
public $m = 'foo';
}
$a = new not_copy_on_write;
$b = $a;
$a->m = 'bar';
echo "\$a->m = $a->m, \$b->m = $b->m\n";
?>
It may be nice to put examples like these into the manual.
Thanks,
