数组和对象转换为json

";
	//一维数组转换json
	$arr1 = array("username"=>"zhangsan","age"=>"100");
	$arr12Json = json_encode($arr1);
	print_r($arr1);
	echo "
";
	print_r($arr12Json);
	
	//二维数组转换json
	$arr2 = array(array("name"=>"zhangsan","age"=>"25"), 
	            array("name"=>"lisi","age"=>"26"),
			    );
	$arr2tojson = json_encode($arr2);			
	echo "
";
	print_r($arr2)."
";;
	echo "
";
	print_r($arr2tojson);
	
	//对象转换到json（只转换共有变量，私有变量和函数不转换）
	class demo
	{
		public $public_name = "piblic name";
		protected $protected_name = "protected name";
		private $private_name ="private name";
		
		public function getName()
		{
			return $this->name;
		}
		
	}
	
	$demo = new demo();
	$objToJson = json_encode($demo);
	echo "
";
	print_r($demo);
	print_r($objToJson);
	
	
	
?>
