Question

这是一个php项目。但是不明白什么类型的数据。

我想把它解析为json。

a:10:{i:1;s:2:"49";i:2;s:2:"53";i:3;s:3:"140";i:4;s:2:"53";i:5;s:2:"53";i:6;s:2:"40";i:7;s:2:"40";i:8;s:2:"60";i:9;s:2:"40";i:10;s:0:"";}

Answer 1

它被称为 serialized data

1。您可以unserialize()将其转换为数组

<?php

$data = 'a:10:{i:1;s:2:"49";i:2;s:2:"53";i:3;s:3:"140";i:4;s:2:"53";i:5;s:2:"53";i:6;s:2:"40";i:7;s:2:"40";i:8;s:2:"60";i:9;s:2:"40";i:10;s:0:"";}';

$unserialized_array = unserialize($data);

print_r($unserialized_array);

输出： - https://eval.in/993433

2。您可以使用json_encode()将其削减为json

<?php

$data = 'a:10:{i:1;s:2:"49";i:2;s:2:"53";i:3;s:3:"140";i:4;s:2:"53";i:5;s:2:"53";i:6;s:2:"40";i:7;s:2:"40";i:8;s:2:"60";i:9;s:2:"40";i:10;s:0:"";}';

$json_data = json_encode(unserialize($data));

echo $json_data;

输出： - https://eval.in/993437

Answer 2

这是序列化数据;您可以使用unserialize获取内容;

$a = 'a:10:{i:1;s:2:"49";i:2;s:2:"53";i:3;s:3:"140";i:4;s:2:"53";i:5;s:2:"53";i:6;s:2:"40";i:7;s:2:"40";i:8;s:2:"60";i:9;s:2:"40";i:10;s:0:"";}';
print_r(unserialize($a));

返回：

   Array ( 
      [1] => 49 
      [2] => 53           
      [3] => 140 
      [4] => 53 
      [5] => 53 
      [6] => 40
      [7] => 40 
      [8] => 60 
      [9] => 40 
      [10] =>
 )

然后你可以在你现在的序列化数据上运行json_encode()来获得你想要的输出......

 $a = 'a:10:{i:1;s:2:"49";i:2;s:2:"53";i:3;s:3:"140";i:4;s:2:"53";i:5;s:2:"53";i:6;s:2:"40";i:7;s:2:"40";i:8;s:2:"60";i:9;s:2:"40";i:10;s:0:"";}';

echo json_encode(unserialize($a));

返回：
{"1":"49","2":"53","3":"140","4":"53","5":"53","6":"40","7":"40","8":"60","9":"40","10":""}

Answer 3

它是序列化数据;您可以反序列化它并转换为json;

<?php
$data = 'a:10:{i:1;s:2:"49";i:2;s:2:"53";i:3;s:3:"140";i:4;s:2:"53";i:5;s:2:"53";i:6;s:2:"40";i:7;s:2:"40";i:8;s:2:"60";i:9;s:2:"40";i:10;s:0:"";}';
echo json_encode(unserialize($data));

它是example，只需按下执行即可获得你的json;

这种数据类型是什么？
