Question

I am completely stumped on what appears to be a trivial problem.

I have this function:

function findCategoryNameInTree($id, $tree) {
    foreach($tree as $branch) {
        if ($branch['category_id'] == $id) {
             echo $branch['name'];//works
             print_r($branch['name']);//works
             //return($branch['name']); //returns nothing
             return $branch['name'];//fix this line per feedback still no return value
        } else {
            if(count($branch['children']) > 0) {
                findCategoryNameInTree($id,$branch['children']);
            }
        }

    }
}

I can’t figure out for the life of me why it’s not returning anything.

Please help!

Edit
Here’s how I call my function

//what I really want to do
$primgenre = findCategoryNameInTree($cat_id,$category_tree['children']);

//but this doesnt work either
echo $primgenre;

//nor this
print_r($pringenre);

You forget to return for this :-

findCategoryNameInTree($id,$branch['children']);

Change :-

return findCategoryNameInTree($id,$branch['children']);
