Need some help to determine the amount of recursive calls in PHP
- by Ben Fransen
Hi all,
I've got a, I think fairly easy question, but this is bugging me for a while now. So I figured, maybe I can get some help here.
Since recursive functions are always a bit tricky, and sometimes a bit unclear to me, I keep struggling to create a nice working solution to get my menudata.
In one of my classes I have this function, which gives me all menu-items recursivly. The thing I want is to determine at which recursionlevel a certain object was retrieved so I can create a nicely looking HTML output with indents for the levels of nesting.
public function GetObjectList($parentID = 0, $objectlist = null)
{
if(is_null($objectlist))
{
$objectlist = new ObjectList("Model_Navigation");
}
$query = MySQL::Query("SELECT * FROM `Navigation` WHERE `WebsiteID` = ".SITE_ID. " AND `LanguageID` = ".LANG_ID." AND `ParentID` = ".$parentID);
while($result = MySQL::FetchAssoc($query))
{
$object = new Model_Navigation();
$object->ID = $result["ID"];
$object->WebsiteID = $result["WebsiteID"];
$object->LanguageID = $result["LanguageID"];
$object->ParentID = $result["ParentID"];
$object->Name = $result["Name"];
$object->Page = Model_Page::GetObjectByID($result["PageID"]);
$object->ExternalURL = $result["ExternalURL"];
$object->Index = $result["Index"];
$object->Level = [here lies my problem];
$objectlist->Add($object);
self::GetObjectList($object->ID, $objectlist);
}
return $objectlist;
}
Hope to hear from you!
