Database file configuration of php development message board

Connecting to the database

Writing ideas

Create a new file conn.php to set up the connection database file

<?php
 $conn =mysql_connect("localhost", "root", "123456789") or die("数据库链接错误");
 mysql_select_db("bbs", $conn);
 mysql_query("set names 'utf8'"); //使用utf-8中文编码;
 ?>

root fill in the user name of mysql 123456789 can fill in your own database password

or die("Database link error"); Make a judgment

mysql_select_db("bbs", $conn);
Fill in the name of the table in your own database at the position of bbs

The file requires a database connection. You only need to call the conn.php file to use it, which is very convenient.
