This is a recursive method of doing it that should be able to cope with the multi-dimensional arrays that are allowable in php4. -robin <?php function cleanup( &$value, $key ) { if (is_array($value)) { array_walk( $value, "cleanup" ); } else { $value = strip_tags($value); } } $CLEAN_POST_VARS = $HTTP_POST_VARS; array_walk( $CLEAN_POST_VARS, "cleanup_tags" ); extract( $CLEAN_POST_VARS, EXTR_OVERWRITE ); ?> -- Robin Vickery...............................................
