Php Tutorial preg_match supports line feed regular expressions

If it is based on the content itself, and then write the mode by yourself, why do we need to write such a strange mode. Even if the original content has a line feed, you can also choose not to use a line feed. If the mode has a database tutorial

/<Span class = "realm tip" id = "profile-info-realm" data-battlegroup = "(. *)">
(. *) </Span>/I

Reference Code 2

Preg_match ('/<span class = "realm tip" id = "profile-info-realm" data-battlegroup = "(. *)">

(. *) </Span>/I'
, $ Replacestr, $ match );

The first parameter is the mode.
"/Regular/s"

$ Pat = "/<span class =" realm tip "id =" profile-info-realm "data-battlegroup =" (. *) ">
(. *) </Span>/is"
