使用vlucas/phpdotenv但是在database里面无法使用$_ENV

tzbob888 更新于5天前

问题描述

试了一下
1.getenv() env()都可以使用唯独 $_ENV会报错
2.$_ENV database.php里面无法读取，但是控制器里面可以使用 echo var_dump输出

env可能是使用了Illuminate\Support\Env才ok的，这里不做讨论，只是想弄清楚为什么 $_ENV会报错，是启动顺序的问题？但是bootstrap.php里面已经在安装dotenv的时候自动做了设置啊

这是bootstrap.php

use Dotenv\Dotenv;
use support\Log;
use Webman\Bootstrap;
use Webman\Config;
use Webman\Middleware;
use Webman\Route;
use Webman\Util;
use Workerman\Events\Select;
use Workerman\Worker;

$worker = $worker ?? null;

if (empty(Worker::$eventLoopClass)) {
Worker::$eventLoopClass = Select::class;
}

set_error_handler(function ($level, $message, $file = '', $line = 0) {
if (error_reporting() & $level) {
throw new ErrorException($message, 0, $level, $file, $line);
}
});

if ($worker) {
register_shutdown_function(function ($startTime) {
if (time() - $startTime <= 0.1) {
sleep(1);
}
}, time());
}

if (class_exists('Dotenv\Dotenv') && file_exists(base_path(false) . '/.env')) {
if (method_exists('Dotenv\Dotenv', 'createUnsafeMutable')) {
Dotenv::createUnsafeMutable(base_path(false))->load();
} else {
Dotenv::createMutable(base_path(false))->load();
}
}

这是database.php
return [
// 默认数据库
'default' => 'mysql',

// 各种数据库配置
'connections' => [
    'mysql' => [
        'driver'      => 'mysql',
        'host'        => getenv('DB_HOST'),
        'port'        => getenv('DB_PORT'),
        'database'    => env('DB_DATABASE'),
        'username'    => $_ENV['DB_USERNAME'],
        'password'    => $_ENV['DB_PASSWORD'],
        'prefix'      => $_ENV['DB_PREFIX'],
        'unix_socket' =>  '',
        'charset'     => 'utf8mb4',
        'collation'   => 'utf8mb4_0900_ai_ci',
        'strict'      => true,
        'engine'      => null,
    ],
],

];

程序代码

问题能解决但是想知道原因
解决方式1  variables_order = "GPCS"  改为 variables_order = "EGPCS"  在php.ini中
解决方式2 使用 env（）    由Illuminate\Support\Env 提供
解决方法3 使用 $_SERVER    如果不想改php.ini的话
