http://www.php.net/manual/en/language.types.array.php If you check out the documentation on arrays, you will see the second code example shows the expected behavior of arrays in this case. $arr = array("foo" => "bar", 12 => true); echo $arr["foo"]; // bar echo $arr[12]; // 1 Now, since each element can be indexed by either a string or an integer, then you can do something like this: $arr = array("1.2" => array(1,2,3,4)); $arr[0] = & $arr["1.2"]; That would set up your doubly indexed array so that you could use either associative keys or numeric keys. http://www.php.net/manual/en/language.references.php PHP.net can explain how references work better than I can. Basically it creates a "symbolic link" (to use a *nix term) to the key "1.2". It shouldn't take up too much memory to do that. -- Ray Hauge Application Development Lead American Student Loan Services www.americanstudentloan.com -----Original Message----- From: Fredrik Thunberg [mailto:thunis@xxxxxxxxxxxxxxxxxxx] Sent: Friday, December 01, 2006 8:52 AM To: Brian Dunning; php-general@xxxxxxxxxxxxx Subject: Re: EZ array problem - What's wrong with my brain?
