使用localhost中的php连接到db [英] Connection to db using php in localhost

问题描述

即使我已经使用了LAMPP多次，这时候出了问题。当我访问浏览器（chrome）没有回波。这是我的代码：

Even if I have used LAMPP many times, this time something goes wrong. When I visit the browser(chrome) nothing echos. Here is my code:

index.php

<?php

error_reporting(E_ALL); /*after edit*/
$link = mysqli_connect('localhost', 'root', 'root', 'db');
if (!$link) {
    die('Could not connect: ' . mysqli_error());
}
echo 'Connected successfully';
mysqli_close($link);

?>

我错过了什么吗？输出是什么。在我写我的文件

Do I miss something? The output is nothing. By the way i write my files in

$

我这样调用： localhost / my_pages 。简单的回波正在工作，php一般是罚款。我的数据库连接出现问题。

and i call it this way: localhost/my_pages. Simple echos are working and php in general is fine. Something goes wrong with my db connection.

推荐答案

感谢大家的回复！我发现了问题。出错了，mysqli在php中没有启用。这是为什么我有这个错误致命错误：调用未定义的函数mysqli_connect（）在/var/www/html/diamond/index.php第8行我重新安装php和问题已解决：）

Thanks everyone for the response! I found the problem. Something went wrong and mysqli wasn't enabled in php. That's why i had this error Fatal Error:Call to undefined function mysqli_connect() in /var/www/html/diamond/index.php on line 8 I reinstalled php and problem solved :)
