I'm trying to refer to value below:
 => stdClass Object (
[label] => Nancy Adler
[attributes] => Array (
[class] => sf-level-0 sf-item-14
[value] => adler-nancy
[depth] => 0
[count] => 3
 =>... etc.
Tough to say with your formatting. but:
The first element in the array is of type
stdClass Object, so to access its members, you use the object accessor
-> rather than the array syntax.
PS: Kudos to Marc for making things legible with his edit.
