phpmyadmin 数据库连接

Question

我正在尝试连接到 MySQL 数据库，但是出现错误。

代码:

<?php
    ini_set('mysql.connection_timeout',300);
    ini_set('default_socket_timeout',300);
    define('DB_SERVER', 'localhost:8080');
    define('DB_USERNAME', 'root');
    define('DB_PASSWORD', '');
    define('DB_DATABASE', 'sib');
    $db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
?>

这给了我错误:

Warning: mysqli_connect(): MySQL server has gone away in C:\xampp\htdocs\SIB\connect.php on line 9

Warning: mysqli_connect(): Error while reading greeting packet. PID=10696 in C:\xampp\htdocs\SIB\connect.php on line 9

Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\xampp\htdocs\SIB\connect.php on line 9

Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\SIB\connect.php on line 9

Answer 1

首先，您的端口必须指定为 mysqi_connect 的单独参数，而不是与主机一起指定。 - 第二件事是您没有连接到 MySQL，而是连接到 Apache 服务器。如果您没有更改 MySQL 端口，只需使用 define('DB_SERVER', 'localhost'); 代替 define('DB_SERVER', 'localhost:8080');

<?php 
     ini_set('mysql.connection_timeout',300);
     ini_set('default_socket_timeout',300);
     define('DB_SERVER', 'localhost');
     define('DB_USERNAME', 'root');
     define('DB_PASSWORD', '');
     define('DB_DATABASE', 'sib');
     $db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE,3306);
