我有3节课。[1]单例 [2]加载 [3]仪表板。在 Load 类中,有一种方法称为“model()”。我正在使用此代码初始化单例对象的数据。
$obj = Singleton::getInstance();
$obj->insertData('email', 'mail@domain.com');
同样,在 Dashboard 类中,有一个名为“show()”的方法,我正在尝试打印 Singleton 对象数据。但是,在这里我可以看到 Singleton 对象的所有数据,除了由“Load”类的“model”方法初始化的数据。
这是我的完整代码...
<?php
//---Singletone Class---
class Singleton
{
// A static property to hold the single instance of the class
private static $instance;
// The constructor is private so that outside code cannot instantiate
public function __construct() {
if(isset(self::$instance))
foreach(self::$instance as $key => &$val)
{
$this->{$key} = &$val;
}
}
// All code that needs to get and instance of the class should call
// this function like so: $db = Database::getInstance();
public static function getInstance()
{
// If there is no instance, create one
if (!isset(self::$instance)) {
$c = __CLASS__;
self::$instance = new $c;
}
return self::$instance;
}
// Block the clone method
private function __clone() {}
// Function for inserting data to object
public function insertData($param, $element)
{
$this->{$param} = $element;
}
}
//---LOAD class---
class Load
{
function __construct()
{
$obj = Singleton::getInstance();
$obj->insertData('country', 'INDIA');
}
function model()
{
$this->name = 'Suresh';
$obj = Singleton::getInstance();
$obj->insertData('email', 'mail@domain.com');
}
function msg()
{
return('<br><br>This message is from LOAD class');
}
}
$obj = Singleton::getInstance();
$load = new load();
$obj->load = $load;
//---Dashboard Class---
class Dashboard extends Singleton
{
function __construct()
{
parent::__construct();
}
function show()
{
echo "Default data in current Object";
echo "<br>";
print_r($this);
echo $this->load->msg();
$this->load->model();
echo "<br><br>Data in current Object after post intialization";
echo "<br>";
print_r($this);
}
}
$dashboard = new dashboard();
$dashboard->show();
