PHP属性复制

if(!function_exists("copy_properties"))
{
	function copy_properties($fromObj,$toObj)
	{
		foreach($fromObj as $key=>$value)
		{
			if(is_array($toObj))
			{
				$toObj[$key] = $value;	
			}
			else if(is_object($toObj))
			{
				if(property_exists($toObj,$key))
				{
					$toObj->$key = $value;
				}
			}
		}
		return $toObj;
	}
}

   

    demo如下：

 

<?php

if(!function_exists("copy_properties"))
{
	function copy_properties($fromObj,$toObj)
	{
		foreach($fromObj as $key=>$value)
		{
			if(is_array($toObj))
			{
				$toObj[$key] = $value;	
			}
			else if(is_object($toObj))
			{
				if(property_exists($toObj,$key))
				{
					$toObj->$key = $value;
				}
			}
		}
		return $toObj;
	}
}

function pre_dump($obj)
{
	echo "<pre>";
	var_dump($obj);	
	echo "</pre>";
}


class TestVo
{
	public $id;
	public $name;
	public $age;
}

function test()
{
	$test_array = array(
		"id" 	=> 1,
		"name"	=> "ongsh",
		"age"	=> 25
	);
	
	//数组到对象
	$vo = copy_properties($test_array,new TestVo());
	pre_dump($vo);
	
	//对象到对象
	$newVo = copy_properties($vo,new TestVo());
	pre_dump($newVo);
	
	//数组到对象
	$arr = copy_properties($newVo,array());
	pre_dump($arr);
	
	//数组到数组
	$newArr = copy_properties($arr,array());
	pre_dump($newArr);
	
}


//execute
test();


?>

 

   页面输出：

object(TestVo)#1 (3) {
  ["id"]=>
  int(1)
  ["name"]=>
  string(5) "ongsh"
  ["age"]=>
  int(25)
}

object(TestVo)#2 (3) {
  ["id"]=>
  int(1)
  ["name"]=>
  string(5) "ongsh"
  ["age"]=>
  int(25)
}

array(3) {
  ["id"]=>
  int(1)
  ["name"]=>
  string(5) "ongsh"
  ["age"]=>
  int(25)
}

array(3) {
  ["id"]=>
  int(1)
  ["name"]=>
  string(5) "ongsh"
  ["age"]=>
  int(25)
}
