i am using this expression instead of i mentioned above, but this one directly converts a text to url without syntax "$msg = preg_replace( "`((http)+(s)?:(//)|(www\.))((\w|\.|\-|_)+)(/)?(\S+)?`i", "<a target=_blank href=\"http\\3://\\5\\6\\8\\9\" title=\"\\0\">\\5\\6</a>", $msg);" and it doesnt adds my site's url. what is the difference?

hi all, i am a newbie member of php world, i need to learn the answer of a simple question why "preg_replace('/\@!$@&()\'*+,;=%]+)"\](.+)\[\!url\]/', '<a href="$1">$2</a>', $string)" expression adds my own site address at the beginning of the link created? such as http://www.mysite.com/www.thesitepreg_replace_created.com
