config

建立範例档 config/myconfig.php

<?phpreturn [    'param1' => 'value1','param2' => [    'param2-1' => 'value2']];

读取设定

config('设定档名.变数名')

Route::get('test', function(){  return config('myconfig.param1')."<br/>".config('myconfig.param2.param2-1');});

http://localhost/test 执行结果 (view)

value1value2

修改设定

config(['设定档名.变数名' => '值'])

Route::get('test', function(){  config(['myconfig.param1' => 'newvalue']);  return config('myconfig.param1');});

http://localhost/test 执行结果 (view)

newvalue

引用.env内容

env('名称', 预设值)

Route::get('test', function(){  config(['myconfig.param1' => json_encode(env('APP_DEBUG', false))]);  return config('myconfig.param1');});

http://localhost/test 执行结果 (view)

true

使用预设值的範例

Route::get('test', function(){  config(['myconfig.param1' => json_encode(env('APP_TEST', false))]);  return config('myconfig.param1');});

http://localhost/test 执行结果 (view)

false

不建议由程式直接读取.env内容，若有因环境而异的设定存在时

将设定值放入.env由config引用.env，并给予预设值程式存取config
