hi, just fixed a bug in serialize and found out that it
reports leaks which are unrelated to my fix, but have more to
do with passing objects to functions.
i'm sure it didn't use to do that.
coments?
tc
<?
class a
{ var $a=1;
var $b;
function __sleep()
{ return array("a","b");
}
}
$a = new a;
var_dump($a);
$b = serialize($a); // serialize uses call_user_function() to call __sleep() in $a
/*
if the above line reads:
$b = serialize(&$a);
we get no leak.
*/
?>
output is:
