數(shù)據(jù)庫連接
1,新建conn.inc.php文件:
定義數(shù)據(jù)庫連接常量如下:
<?php
define("HOST",'localhost');
define("USER",'root');
define("PWD",'root');
define("DBNAME",'onecms');2,新建mysqli.php文件:
<?php
include 'conn.inc.php';
$mysqli=new mysqli(HOST,USER,PWD,DBNAME);
if($mysqli->connect_errno){
die('數(shù)據(jù)庫鏈接出錯'.$mysqli->connect_error);
}下次連接數(shù)據(jù)庫操作只需要引進(jìn)mysqli.php文件即可
