calling a function from within a function

Fi_C**

Hi All,
I know this is a pretty straightforward procedure!
That is why I am so puzzled as to why this won't work for me. It's php but it should work the same way as c++ would;
I have a function called printMenuLevel($var)
//where $var is an object
I then have this function:

function trail($var)
{
$thatURL = $var->url;
echo($thatURL);
echo("<br>");
if ($thatURL == $thisURL ){ //this cond defn does not fail!
printMenuLevel($arr[1]);
}
while(list($key, $value)= each($menuLevel->children))
{
trail($value);
}
}
trail($arr[1]);

Any ideas why printMenuLevel is not called
thanks

Where does the array $arr come from? From outside the function (in which case it should be declared as global) or it this a typo and you should be refrencing $var?

$arr is an array within class var


$root_menu = new var ( "Home", "piqs.php", $arr = array(
new var( "Admin", "piqs.htm", array(
new var ("Manage Tests", ....

and so on ...

var is a class :

class var
{
var $title;
var $url;
var $children;

function var ($title, $url, $children=null)
{
$this->title = $title;
$this->url = $url;
$this->children = $children;
}
}

thanks

Have you tried putting in some echo statements in the printMenuLevel function to see if it's actually getting into the function ?

Also, shouldn't you have printMenuLevel($var->arr[1]);

The code doesn't know what $arr is otherwise
