Cybot, try this .... function string_dryclean($dirtystring) { $cleanstring = str_replace("\n", " ", $dirtystring); $cleanstring = trim(str_replace("\t", " ", $cleanstring)); do { $cleanstring = str_replace(" ", " ", $cleanstring); } while (strpos($cleanstring, " ") > 0); return $cleanstring; } use it like this... $ugly_evil_string = " hello \n\n \n\t world \n\n\t "; $decent_law_abiding_string = string_dryclean($ugly_evil_string); ----- Original Message ----- From: "cybot" <php.net@tekkno4u.de> To: <php-windows@lists.php.net> Sent: Saturday, February 01, 2003 1:58 AM Subject: Re: [PHP-WIN] Something like trim() > is there no more complicated solution for this? ;-) > > nothing for bad! > > B.A.T.
