本篇文章主要介绍了php利用嵌套数组拼接与解析json的方法，内容挺不错的，现在分享给大家，也给大家做个参考。
利用嵌套数组 拼接混合json -包含对象数组
// 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);
?>
php利用嵌套数组 解析混合json 包含对象数组
function json_to_array($web) {
$arr=array();
foreach($web as $k=>$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","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';
$web=json_decode($s);
$arr=json_to_array($web);
echo "
";
print_r($arr);
echo "
";
/************************************************************************

$s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';
$web=json_decode($s);
echo '网站名称：'.$web->webname.'
网址：'.$web->url.'
联系方式：QQ-'.$web->contact->qq.' MAIL:'.$web->contact->mail;
echo '

$s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';
$web=json_decode($s);
echo json_encode($web);
$mys='{"status":"0","message":"ok","arr":[{"name":"ren","age":0},{"name":"ren","age":1},{"name":"ren","age":2},
{"name":"ren","age":3},{"name":"ren","age":4},{"name":"ren","age":5},{"name":"ren","age":6},{"name":"ren","age":7},
{"name":"ren","age":8},{"name":"ren","age":9}]}';
$myweb=json_decode($mys);
echo $myweb->status;
for($i=0;$i<10;$i++)
{
echo $myweb->arr[$i]->age;
echo '
';
}
?>
