How to include some file inside a laravel controller
提问by Belmark Caday
I have a file that calculates something, lets say tax. Tax.php, this is inside some folder, lets say /MyCalculations/Taxes/Tax.php.
我有一个文件可以计算一些东西，比如说税收。Tax.php，这是在某个文件夹内，让我们说/MyCalculations/Taxes/Tax.php。
Now I want this file to be accessible inside my controller, How do I access this file, or how do I access those calculations inside this file?

You could start by creating a namespace for your application, and place a folder in your app directory, perhaps app/Projectname. Then you could place your calculations namespace there there. Then autoload everything in your project by adding
您可以首先为您的应用程序创建一个命名空间，然后在您的应用程序目录中放置一个文件夹，可能是 app/Projectname。然后你可以把你的计算命名空间放在那里。然后通过添加自动加载项目中的所有内容
"autoload": {
"classmap": [
"..."
],
"psr-0": {
"Projectname": "app/"
}
},
to your composer.json file and then do a dump-autoload. Then you could use dependency injection in your controller, like so:
到您的 composer.json 文件，然后执行转储自动加载。然后你可以在你的控制器中使用依赖注入，像这样：
use Projectname\MyCalculations\Taxes\Tax;
class TaxController extends BaseController {
protected $tax;
public function __construct(Tax $tax)
{
$this->tax = $tax;
}
public function getTaxValue()
{
$value = Input::get('value');
return $this->tax->getAwesome($value);
}

Edit your composer.json file and add the 'files' section to it to it:
编辑您的 composer.json 文件并将“文件”部分添加到其中：
"autoload": {
...
"files": [
"app/MyCalculations/Taxes/Tax.php"
]
},
Then you just have to execute:
然后你只需要执行：
composer dump-autoload
And use them everywhere.
并在任何地方使用它们。
If you are on PHP 5.5, you also can use traits:
如果您使用的是 PHP 5.5，您还可以使用特征：
<?php namespace MyCalculations/Taxes;
trait TaxesTraits {
function calculateX()
{
}
}
class Taxes extends Enginge {
use TaxesTraits;
public function calculate()
{
$x = $this->calculateX();
}
}
