<?php
function getMysqlConnection($host, $user, $pass, $database) {
global $mysqli;
global $Mysqlerror;
$mysqli = new mysqli('$host', '$user', '$pass', '$database');
if (empty($mysqli->connect_errorno) == false) {
$Mysqlerror = "true";
} else {
$Mysqlerror = "false";
}
}
我创建了一个如上所述的函数，它实现了给定 MySQL 用户凭据的连接，我通过使用实现了这个函数
<?php
require 'myFunc.php';
getMysqlConnection("localhost", "wronguser", "wrongpass", " test");
echo $Mysqlerror;
虽然我使用了错误的密码和用户名，但 Mysqlerror 是错误的。我也用过 or die function 没有任何反应
Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /opt/lampp/htdocs/mysite/myFunc.php on line 5
Warning: mysqli::mysqli(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known in /opt/lampp/htdocs/mysite/myFunc.php on line 5
我像往常一样重新启动了 lampp

我的代码或服务器有问题吗？如何解决？
