How to connect php to mysql database

Tags php database mysql database

$ Localhost = 'localhost'; // connect to the server. In most cases, use localhost,
$ User = 'root'; // mysql logon account
$ Upwd = '000000'; // logon password of the mysql server
$ Db = 'DB'; // your mysql database


The code is as follows: Copy code
$ Conn = mysql_connect ($ localhost, $ user, $ upwd) or die (mysql_error (). 'MySQL data connection failed ');
Mysql_select_db ($ db, $ conn) or die ('database does not exist'. mysql_error ());

// The above is a simple connection method between mysql and the php database, and a slightly intrusive connection code is coming down.

$ Liketype = 'p'; // determines whether a persistent connection or a temporary connection is used.
$ Charset = 'gbk'; // sets the encoding for connecting to the mysql database. In this way, no garbled code occurs when connecting to the database.

The code is as follows: Copy code
Try {
If ('P' = $ links)
$ Conn = mysql_pconnect ($ localhost, $ user, $ upwd) or die (mysql_error ());
$ Conn = mysql_connect ($ localhost, $ user, $ upwd) or die (mysql_error ());
Mysql_select_db ($ db, $ conn );
Mysql_query ("set names '$ charset '");
} Catch (exception $ e ){
Echo 'database connection failed. Please contact related personnel! ';
