Can you use a comma in a PHP array key?

I'm wanting to make a PHP array and use people's names as keys mapping to employee ID numbers. Example:

$staffID = array(
   "Doe, Jane" => 124, 
   "Smith, John" => 876
);

I'd like to keep them LastName, FirstName so that I can easily peruse down the list later on. I'm concerned about those commas in the keys though. Is this valid in PHP?

Yes, they're just strings. You can have any valid string (or integer) as an array key.
