php利用嵌套数组拼接与解析json的方法

利用嵌套数组   拼接混合json -包含对象数组

<?php

// 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

<?php
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]=$v;
echo "<pre>";
print_r($arr);
echo "</pre>";

$s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"[e-mail]","xx":"xxxxxxx"}}';
$web=json_decode($s);
$arr=json_to_array($web);
echo "<pre>";
print_r($arr);
echo "</pre>";

$myweb=json_decode($mys);

echo $myweb->status;

for($i=0;$i<10;$i++)
{
 echo $myweb->arr[$i]->age;
 echo '<br /><br />';
}
?>
