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,
