RegEx can be expensive. Always ask "do I need one?" In this case, use a string find to locate the // and the following \n (or whatever marks the end of line on your/supported OpSys), then substring or string replace. If would be quite interesting to see a performance comparison on this - if you've got time... =dn PS if you were working with alpha-text and had to consider upper and lower case, then things might sound very different! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
