找不到 phpmyadmin 主机!

Question

您好，我正在使用 xampp，我正在尝试使用 php 进行连接。

<?php $server = localhost; $username = root; $password = ******;?>

$sql_connections = mysql_connect("$server, $username, $password") or die(mysql_error());

Warning: mysql_connect() [function.mysql-connect]: php_network_getaddresses: getaddrinfo failed: Host desconocido. in C:\xampp\htdocs\Database Manager\admin\sql_functions.php on line 17

Warning: mysql_connect() [function.mysql-connect]: [2002] php_network_getaddresses: getaddrinfo failed: Host desconocido. (trying to connect via tcp://localhost, root, usd27498:3306) in C:\xampp\htdocs\Database Manager\admin\sql_functions.php on line 17

Answer 1

您使用了不正确的符号来设置服务器:

 mysql_connect("$server, $username, $password")

需要

 mysql_connect($server, $username, $password)

manual on mysql_connect
