Question

我在files内的目录custom中有自定义App。一个文件名为update.php，因此路径为

App\custom\update.php

在update.php中我有

$config = include __DIR__ . '/../../app/config/database.php';

$servername = $config['connections']['mysql']['host'];
$username   = $config['connections']['mysql']['username'];
$password   = $config['connections']['mysql']['password'];
$dbname     = $config['connections']['mysql']['database'];

其中读取数据库凭据。这完全适用于Laravel 4.2，但在Laravel 5.4中不起作用

对于Laravel 5.4，我已经改变了

的路径

$config = include __DIR__ . '/../../../config/database.php';

但错误显示此../../../而不是执行它

include(/var/www/html/site/app/custom/../../../config/database.php): failed to open stream: No such file or directory

我怎样才能正确地给出路径？

更新：当前代码database.php

    'mysql' => [
        'driver' => 'mysql',
        'host' => 'localhost',
        'port' => '3306',
        'database' => 'test',
        'username' => 'root',
        'password' => '123321',
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],

在update.php中

$config = config_path('database.php');

$servername = config('database.connections.mysql.host');
$username = config('database.connections.mysql.host');
$password = config('database.connections.mysql.host');
$dbname = config('database.connections.mysql.host');


$conn = new mysqli($servername,$username,$password,$dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

Answer 1

您不必包含该文件，而是使用辅助方法config()

$servername = config('database.connections.mysql.host');

Answer 2

如果您真的想要加入它，可以使用config_path()：

$path = config_path('database.php');

在Laravel中获得正确的路径
