php利用嵌套数组拼接与解析json的方法

// 自 PHP 5.4 起
$array = [
"status" => "0","message" => "ok","arr"=> []
];

class Person {
public $name;
public $age;

//定义一个构造方法初始化赋值
public function __construct($name,$age) {
$this->name=$name;
$this->age=$age;
}
}

for($i=0;$i<10;$i++)
{
$p=new Person("ren",$i);
$array["arr"][]=$p;
}

//var_dump($array);

echo json_encode($array);

?>

$v) { if(is_object($v)) $arr[$k]=json_to_array($v); //判断类型是不是object else $arr[$k]=$v; } return $arr; } $s='{"webname":"homehf","url":"www.homehf.com","qq":"744348666"}'; //将字符转成JSON $web=json_decode($s); $arr=array(); foreach($web as $k=>$v) $arr[$k]=$v; echo "

";  
print_r($arr);  
echo "

";

$s='{"webname":"homehf","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';
$web=json_decode($s);
$arr=json_to_array($web);
echo "

print_r($arr);

echo "
