Re: getting the "next" element of an associative array

let's say we have the following associative array: $array = array( "red" => "ferrari", "yellow" => "volkswagen", "green" => "mercedes", "blue" => "volvo" ); then we have a current index into the array: $index = "yellow"; $current = $array[$index]; now: how do i get the key of the next array element (in this case "green")? $next = ? Give this a shot

<?php function array_next($ar, $curr) { $capture = false; $next = ''; foreach ( $ar AS $k => $v ) { if ( $capture ) { return array($k => $v); } if ( $k == $curr ) { $capture = true; } } return $next; } $array = array( "red" => "ferrari", "yellow" => "volkswagen", "green" => "mercedes", "blue" => "volvo" ); print_r( array_next($array, 'yellow') );
