  1. Hello guys, first post here.

    I am really desparate about how references (do not) work in PHP.

    Here's a code snippet:

    [code]
    var $data;
    var $_children;
    var $_uniqueNames;

    function &add(&$child) {
    $name = $child->data->name;
    if (array_key_exists($name, $this->_uniqueNames)) {
    return $this->_uniqueNames[$name];
    }
    $this->_children[] =& $child;
    $this->_uniqueNames[$name] =& $child; // we register the name
    $true = TRUE;
    return $true;
    }
    [/code]

    This is part of a simple Node class prepared to build trees. A Node remembers the names of its children and refuses to add a new child with a name already registered. Everything seems to work except the return value in case there is an attempt to add a child with an already registered name -- my client code always gets NULL whatever I do!
    I would appreciate any idea of why is that and how can I fix it, thanks in advance!
