Strange PHP reference bug
- by Roland Soós
Hello,
I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work.
Contructor:
function Menu(&$menus, &$keys , &$parent, &$menu){
...
if($keys === NULL){
$keys = array_keys($menus);
}
...
for($x = 0; $x < count($keys); $x++) {
var_dump($keys);
$menu = $menus[$keys[$x]];
var_dump($keys);
if($this->id == $menu->pid){
$keys[$x] = NULL;
$this->submenus[] = new Menu($menus, $keys, $this, $menu);
}
}
First var_dump give me back the array, the second give back the first element of $menus. Do you have any idea what causes this?
PHP version 5.2.3
