Question

I’m trying to sort my array and I keep getting a result of 1

here is the code pleas help

            $foo = array(
                2 => "Sports",
                40 => "Parent and Families",
                43 => "Arts and Entertainment",
            );
            $foo = sort($foo);

I’d like them to be sorted by value

Answer 1

Sort doesn’t return the sorted array. It returns TRUE of FALSE on success. The array is passed by reference. So call the method and just use it

$foo = array(
                2 => "Sports",
                40 => "Parent and Families",
                43 => "Arts and Entertainment",
            );
            sort($foo); //foo is now sorted 

EDIT

Note however, that sort() actually reassigns your indices. You should use asort() instead of sort if you want to keep associations
