I want to do a split/explode on: "hello world with a lot of whitespaces!" on spaces... in such a manner that when I join/implode it back together I get: "hello world with a lot of whitespaces!" not: "hello world with a lot of whitespaces missing!" I'd be happy if I could even get: $myarray = ["hello ", "world ","with ","a ","lot ", "of ","whitespaces!"] 'cause I could spell check based on trimming the entry. -Garth Northern.CA ===-- http://www.northern.ca Canada's Search Engine > > But remark: \t (tabs) will also count as whitespace, but not \n and > \r.
