如何优雅管理PHP应用配置？yosymfony/toml助你轻松驾驭TOML格式

composer require yosymfony/toml

<?php

require 'vendor/autoload.php'; // 引入 Composer 自动加载

use YosymfonyTomlToml;

$tomlString = '
name = "My Application"
version = "1.0.0"

[database]
type = "mysql"
host = "localhost"
port = 3306
';

$configArray = Toml::Parse($tomlString);

echo "解析后的配置数组：
";
print_r($configArray);
// 输出：
// 解析后的配置数组：
// Array
// (
//     [name] => My Application
//     [version] => 1.0.0
//     [database] => Array
//         (
//             [type] => mysql
//             [host] => localhost
//             [port] => 3306
//         )
// )

# config.toml
title = "TOML Example"
owner = { name = "Tom Preston-Werner", organization = "GitHub" }

[server]
ip = "192.168.1.1"
ports = [ 8001, 8002, 8003 ]
