PHP和MySQL连接问题 [英] PHP and MySQL Connection Problem

问题描述

我正在尝试通过PHP脚本连接MySQL数据库，但没有发生任何事情成功的消息根本没有打印，我的连接代码如下：



config.php 文件：

I am trying to connect MySQL database via PHP Script but nothing is happening the conncetion Successful message is not printing at all, my code for connection is follows:

config.php file:

<?php

define("DB_HOST","localhost:81");
define("DB_USER","root");
define("DB_PASSWORD,"sandeep");
define("DB_DATABASE","android_api");

?>

DB_Connect 文件：

DB_Connect file:

<?php
 
class DB_Connect {
 
    // constructor
    function __construct() {
         
    }
 
    // destructor
    function __destruct() {
        // $this->close();
    }
 
    // Connecting to database
    public function connect() {
        require_once 'config.php';
        // connecting to mysql
        $con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
        // selecting database
        mysql_select_db(DB_DATABASE);
 
        // return database handler
        return $con;
    }
 
    // Closing database connection
    public function close() {
        mysql_close();
    }
 
}
 
?>

推荐答案

this - >关闭（）;
}

//连接数据库
public function connect（）{
require_once'config.php';
//连接到mysql

this->close(); } // Connecting to database public function connect() { require_once 'config.php'; // connecting to mysql

con = mysql_connect（DB_HOST，DB_USER，DB_PASSWORD）;
//选择数据库
mysql_select_db（DB_DATABASE）;

//返回数据库处理程序
return

con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); // selecting database mysql_select_db(DB_DATABASE); // return database handler return

con;
}

//关闭数据库连接
public function close（）{
mysql_close（）;
}

}

？>

con; } // Closing database connection public function close() { mysql_close(); } } ?>
