This is the method I use to work with flags and their string counter-parts when working on non-OO projects. It's nice because it keeps these flag strings out of global scope, while only using one static copy of the array through the entire lifespan of the script.

<?php
// Data Object Types

                            
 define('OBJECT_TYPE_USER',         1);

                            define('OBJECT_TYPE_CONTACT',     2);

                            

                            function &get_object_types()

                            {

                                static $data = null;

                                if ($data === null) // initialization on first call

                                {

                                    $data = array(

                                        OBJECT_TYPE_USER => 'User',

                                        OBJECT_TYPE_CONTACT => 'Contact'

                                        );

                                }

                            

                                return $data;

                            }
?>

Usage Example

if (isset($_POST['type']))

                            {

                              $flags = $_POST['type'];

                              $a =& get_object_types();

                              echo 'This is a ', $a[$otype],' type.';
