In addition to returning the wrong value the code produces a number of
memory leaks that are listed below.

I'm using PHP 4.2.3 on Windows NT 5.0 build 2195 (win2k)
along with Apache and stumbled across a strange behaviour
regarding return() arguments in parentheses.
Consider the following code:
class Node {
var $children;
var $name;
function Node($name) {
$this->children = array();
$this->name = $name;
}
function &add($n) {
$this->children[0] = $n;
return($this->children[0]); # these () make a difference
}
}
$t = new Node("top");
$node = new Node("foo");
$n = &$t->add($node);
$n->name = "bar";
print $n->name; # output: "bar"
print $t->children[0]->name; # output: "foo"
The code is working as expected (i.e., both times
"bar" is printed) when you remove the
parentheses from the return call in the add method.
According to the manual, parentheses in a return
call shouldn't make a difference.
