PHP automatically chooses to connect to the local database or remote database _ PHP Tutorial

PHP automatically chooses to connect to the local database or remote database. For the mysql.class.php file, see www.jb51.netarticle25496.htm. The Copy code is as follows :? Php contains Mysql operation class include_onceMysql.class.php; local mysql data $ mysql_l Mysql. class. php file see http://www.jb51.net/article/25496.htm

The code is as follows:

// Contains the Mysql operation class
Include_once 'MySQL. class. php ';
// Local mysql data
$ Mysql_local_data = array ('Db _ host' => 'localhost ',
'Db _ user' => 'root ',
'Db _ pass' => 'root ',
'Db _ name' => 'test ');
// Remote mysql data
$ Mysql_remote_data = array ('Db _ host' => '61. 183.41.178 ',
'Db _ user' => 'XXX ',
'Db _ pass' => 'XXX ',
'Db _ name' => 'XXX ');
// Public data
$ Tb_prefix = 'php95 _';
$ Db_charset = 'utf-8 ';
// If the local connection is successful, the local Mysql class is instantiated. Otherwise, the local database is connected and the Mysql class is instantiated.
If (@ mysql_connect ($ mysql_local_data [db_host], $ mysql_local_data [db_user], $ mysql_local_data [db_pass])
$ Db = new Mysql ($ db_host, $ mysql_local_data [db_user], $ mysql_local_data [db_pass], $ mysql_local_data [db_name], $ db_charset, $ conn );
Else
$ Db = new Mysql ($ mysql_remote_data [db_host], $ mysql_remote_data [db_user], $ response [db_pass], $ mysql_remote_data [db_name], $ db_charset, $ conn );
$ Db-> show_tables (); // test: displays the names of all tables in the current database.
