This is a function I wrote that runs through a single dimensional array and assigns variables based on the key names.

<?php
function assign_from_array($array) {

                                $keys = array_keys($array);

                                for ($i=0; $i<count($array); $i++) {

                                    $key = $keys[$i];

                                global ${$key};

                                ${$key} = $array[$key];

                                }

                            }
?>

Usage Example

Example if external variables are not global in PHP. Variable "option" with value of "1" is passed to the script via the POST method.


                            

                            echo $HTTP_POST_VARS['option'] // prints "1"

                            echo $option; // prints nothing

                            assign_from_array($HTTP_POST_VARS);

                            echo $option; // prints "1"
