Sorry to forward this to you but I really have problems in
printing a doubled linked class.
Can you take a look at the following message and give me
an answer.

Thanks,

Emanuel Dejanu

Hi,

Is there a posibility to print an object but to not print some fields.

If I use print_r he will print all variabiles from my object, but I want on
variabile to not be printed. I do not want to write my own function.
Ex.

class Node {
        var $name;
        var $parent = '/'
        var $children = array();
        function Node($name, &$parent) {
                $this->parent = &$parent;
                $this->name = $name;
        }
}

$rootNode = new Node('root', '');
array_push($rootNode->children, new Node('child1', $rootNode));
$child1Node = &$rootNode->children[0];
array_push($child1Node->children, new Node('child1', $child1Node));

print_r($rootNode);

will print make a recursivity. What will be nice is to allow that some
variabiles to not
be printed like this:

class Node {
        var $name;
        var $__parent = '/'
        var $children = array();
        function Node($name, &$parent) {
                $this->__parent = &$parent;
                $this->name = $name;
        }
}

..... /* add the root and childrens */

print_r($rootNode);

will print now the corret tree.

Bellow you find the only modification that need to be done for this to work.

Best regards,

Emanuel Dejanu
