Try this: preg_replace( "/^217.215.84.222.*\n/m", "", $log ) The second argument, currently empty, can be used as a replacement string. As we look at the regular expression "/^217.215.84.222.*\n/m", from left to right: ^ Start of line if modifier /m is used (completely right) <ip address>, followed by a dot (.). This dot means any characters, followed by a asterisk (*). The asterisk is a "0 or more quantifier", which matched everything until the next statement (in this case the "\n"). You can also use "$" instead of "\n", only the newline will not be stripped. "$" means end of line, while "\n" means newline. HTH, Erwin
