<? Php class database {private $ hostname; private $ user; private $ pass; private $ dbname; private $ linkflag; private $ charset; function _ construct () {$ this-> hostname = "localhost"; $ this-> user = "root"; $ this-> pass = "111"; $ this-> dbname = ""; $ this-> charset = "utf8"; // gb2312 GBK utf8 $ this-> linkflag = mysql_connect ($ this-> hostname, $ this-> user, $ this-> pass); mysql_select_db ($ this-> dbname, $ this-> linkflag) or die ($ this-> error (); mysql_query ("set names ". $ this-> charset);} function _ set ($ property_name, $ value) {return $ this-> $ property_name = $ value;} function _ get ($ property_name) {if (isset ($ this-> $ property_name) {return $ this-> $ property_name;} else return null;} function _ call ($ function_name, $ args) {echo"
The method you called $ function_name does not exist.
