[英]Is it possible to chain static together with non-static method in PHP?
這是我的示例代碼Class User,但是當我使用public方法添加靜態方法時,它不起作用:
<?php
namespace App\Classic;
class User
{
public $username;
public static $upassword;
public $age;
public $message;
public function username($username)
{
$this->username = $username;
echo $this->username."<br>";
return $this;
}
public static function password($upassword)
{
self::$upassword = $upassword;
echo self::$upassword."<br>";
}
public function age($age)
{
$this->age = $age;
echo $this->age."<br>";
return $this;
}
public function message($message)
{
$this->message = $message;
echo $this->message."<br>";
return $this;
}
}
這是鏈接方法的副作用:
$user = new User();
$user::password('secret')
->username('admin')
->age(40)
->message('lorem ipsum');
我不知道這樣做背后的邏輯是什么,但這個解決方案仍然會有所幫助。
<?php
namespace App\Classic;
ini_set('display_errors', 1);
class User
{
public $username;
public static $upassword;
public static $currentObject=null;//added this variable which hold current class object
public $age;
public $message;
public function __construct()//added a constructor which set's current class object in a static variable
{
self::$currentObject= $this;
}
public function username($username)
{
$this->username = $username;
echo $this->username . "<br>";
return $this;//added this statment which will return current class object
}
public static function password($upassword)
{
self::$upassword = $upassword;
echo self::$upassword . "<br>";
return self::$currentObject;
}
public function age($age)
{
$this->age = $age;
echo $this->age . "<br>";
return $this;
}
public function message($message)
{
$this->message = $message;
echo $this->message . "<br>";
return $this;
}
}
$user = new User();
$user::password('secret')
->username('admin')
->age(40)
->message('lorem ipsum');
