A simple function that takes an array such as HTTP_GET_VARS and creates an url variable string from the elements. This string can then be used in a link to another page. Especially useful for Last Page / Next Page / Modify Search buttons on search pages.

<?php
function array_to_url( $values ){

                            

                                if( !is_array( $values ) ) return false;

                                

                                $url = '';

                                

                                reset( $values );

                            

                                while( list( $k, $v ) = each( $values ) ){

                                

                                    if( !is_object( $v ) ){

                                    

                                        if( is_array( $v ) ){

                                        

                                            reset( $v );

                                            

                                            while( list( $k2,$v2 ) = each( $v ) ){

                                                $url .= $url == '' ? $k.'['.$k2.']='.urlencode( $v2 ) : '&'.$k.'['.$k2.']='.urlencode( $v2 );

                                            }

                                            

                                        }

                                        else{

                                            $url .= $url == '' ? "$k=" . urlencode( $v ) : "&$k=" . urlencode( $v );

                                        }

                            

                                    }

                            

                                }

                                

                                return $url;
