How about array_filter()? From the docs: "If the callback function is not supplied, array_filter() will remove all the entries of input that are equal to FALSE." $a = array ('a' => 'foo', 'b' => '', 'c' => null, 'd' => 99, 'e' => 0); print_r (array_filter ($a)); // Output: Array ( [a] => foo [d] => 99 ) As a previous poster noted, though, this will only work for you if "0" and the empty string et al. are not significant in your application. pb -- paul bissex, e-scribe.com -- database-driven web development 413.585.8095 69.55.225.29 01061-0847 72°39'71"W 42°19'42"N
