php - 在 PHP 中，你如何创建可重用对象？对此有最佳实践吗？你喜欢哪个？

Question

我正在用 php 创建一些可重复使用的对象，我想知道构建它们的最佳方法是什么。下面我有 2 个不同方法的例子。

Class Uploader{
    public $Filename;
    public $Directory;

    function upload(){
        upload_file($this->Filename, $this->Directory)
    }
}

// Then use the class above like this.
$u = new Uploader;
$u->Filename = 'foo.png'; // Set all the props
$u->Directory = 'bar/'    //  ^   ^   ^    ^
$u->upload();             // Then Execute

或者这样做会更好吗...

Class Uploader {
    function uploader($filename, $directory){
        upload_file($filename, $directory)
    }
}

// Then use the class above like this.
$u = new Uploader;
$u->uploader('foo.png', 'bar/') // Obviously much less code, All in One.

在这两种方法中，哪一种是首选，它们是速度差异还是使用一种方法比另一种方法有任何好处？
我赞成示例 #1，但他们是对此的最佳实践吗？

Answer 1

为什么不能两者兼顾？

class Uploader
{
  public
    $filename,
    $directory;

  public function __construct( $name = '', $dir = '', $autoUpload = false )
  {
    $this->filename = $name;
    $this->directory = $dir;
    if ( $autoUpload )
    {
      $this->upload()
    }
  }

  public function upload()
  {
    //check your values
    ...code...
    upload_file( $this->filename, $this->directory );
  }
}

使用这种技术，您可以简单地自动上传文件:

$uploader = new Uploader( $name, $dir, true);

或者您可以手动构建对象:

$uploader = new Uploader();
$uploader->filename = $name;
$uploader->directory = $dir;
$uploader->upload();
