<?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";
} }
?>
我已经创建了一个上面的函数,它实现了给定mysql用户凭据的连接,我使用了实现这个功能
<?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.我也用过或死过的功能都没有发生
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
它像往常一样重新启动了灯泡
