Convert An Array

http://ccl.flsh.usherb.ca/db/authors_under_study.php or $names = array ("john", "mary", "bill", "mary", "bill", "mary", "bill", "john", "bill", "john"); 1) How do I count the elements of $names to produce: bill 4 john 3 mary 3 2) How do I store the counted elements into a new array? How do I create this: $new_array = array ("bill"=>4, "john"=>3, "mary"=>3) I'm looking at http://www.php.net/manual/en/function.array.php but not sure.
