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PHP5.4起
$array=[
"status"=>"0",
"message"=>"ok",
"arr"=>[]
];
classPerson{
public$name;
public$age;
//定义一个构造方法初始化赋值
publicfunction__construct($name,$age){
$this->name=$name;
$this->age=$age;
}
}
for($i=0;$i<10;$i++)
{
$p=newPerson("ren",$i);
$array["arr"][]=$p;
}
//var_dump($array);
echojson_encode($array);
?>
php利用嵌套数组 解析混合json 包含对象数组
<?php
functionjson_to_array($web){
$arr=array();
foreach($webas$k=>$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);
$arr=array();
foreach($webas$k=>$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>";
