这篇文章给大家介绍怎么在php中利用嵌套拼接数组,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。
利用嵌套 拼接数组
<?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":"nieweihf@163.com","xx":"xxxxxxx"}}';
$web=json_decode($s);
$arr=json_to_array($web);
echo "<pre>";
print_r($arr);
echo "</pre>";
/************************************************************************

$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:'.$web->webname.'<br />网址:'.$web->url.'<br />联系方式:QQ-'.$web->contact->qq.' MAIL:'.$web->contact->mail;
echo '<br /><br />';
/************************************************************************

$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 '<br /><br />';
}
?>
