I found a different way. I don't actually think this is better, but the regexp is some what more pure: --- PHP code --- <PRE> <?php $mem = "Hello world! http://www.helloworld.com\n Hello world! ftp://ftp.server.com\n Hello world www.helloworld.com"; /* ------ ! Here's the old regexp ! ------ */ // $mem = preg_replace ("/\s+([http:|ftp:]{0,1}\S+\.\S+)/me", "' <A // href=\"'. // (ereg('^[http:|ftp:]','\\1') // ? '\\1\">\\1</A>' // : 'http://\\1\">http://\\1</A>')", $mem); /* ------ ! Here's the new regexp ! ------ */ // Need an associative array... $repl = array ("" => "http://", "http://" => "http://", "ftp://" => "ftp://"); // The regexp itself: $mem = preg_replace ("/\s+([http:|ftp:]*(\/\/)*)(\S+\.\S+)/me", "' <A href=\"'.\$repl['\\1'].'\\3\">'.\$repl['\\1'].'\\3</A>'", $mem); print ($mem); ?> </PRE> --- End of PHP code --- I'll let you know when I find a better way... I think there must be one... </Reply> -- * R&zE: -- »»»»»»»»»»»»»»»»»»»»»»»» -- Renze Munnik -- DataLink BV -- -- E: renze@datalink.nl -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- Netherlands -- -- http://www.datalink.nl -- ««««««««««««««««««««««««
