Re: Re: split on whitespace, preserving whitespace...

If you'r using PHP >4 use preg_split. (works also with php 3 >= 3.09) see http://www.php.net/manual/en/function.preg-split.php for detailed information. The split pattern you'd need is: $sometext2split = "hello world with a lot of whitespaces!"; $myarray = preg_split ("/\s+/",$sometext2split); you should get $myarray := ['hello', 'world', 'with', 'a', 'lot', 'of', 'whitespaces!'] But remark: \t (tabs) will also count as whitespace, but not \n and \r. See docu for more informations Hope, it helps best regards Stefan Rusterholz, scripting@interaktion.ch ----- Original Message ----- From: "Garth Dahlstrom" <garth@utmail.to> To: <james@towntalk.co.uk> Cc: <php-general@lists.php.net> Sent: Friday, July 20, 2001 1:44 PM Subject: [PHP] Re: split on whitespace, preserving whitespace... > > try $wordarr = explode(" ", $string); > > mmm... yeah...
