json怎么解码成数组输出?
a:2:{i:0;s:21:"www";i:1;s:16:"eee";}

------解决方案--------------------
看json_decode

http://php.net/manual/en/function.json-decode.php


------解决方案--------------------
你确认这是一个正确的Json格式数据?
------解决方案--------------------
数据库里的数据是哪来的?我想他不应该是Json...

探讨

同问
数据库就这样的!
json_decode 用过数组就一个值。

------解决方案--------------------
象serialize的, 
不过还是有点小奇怪
------解决方案--------------------
我测试过,无法正常还原的

探讨

象serialize的,
不过还是有点小奇怪

------解决方案--------------------
这分明不是json
------解决方案--------------------
有cms uchome好像这么储存过数据
------解决方案--------------------
先在这个http://jsonlint.com/ 验证下json格式是否正确,json转换成数组的话用 json_decode
------解决方案--------------------
读出来是这个 array('www','eee'); 但是数组元素的长度不正确
------解决方案--------------------
看这格式不是json,是serialize序列化之后的结果,但数据明显有问题

a:2:{i:0;s:21:"www";i:1;s:16:"eee";};

意思是:一个数组包含两个元素,第一个元素是长为21的字符串www(明显不对,长度应该是3),第二个元素是长为16的字符串eee(也不对)

$str='a:2:{i:0;s:3:"www";i:1;s:3:"eee";}';
var_dump(unserialize($str));
//这应该就对了
------解决方案--------------------
array(2) { [0]=> string(3) "www" [1]=> string(3) "eee" }

Combination of golang WebSocket and JSON: realizing data transmission and parsing Combination of golang WebSocket and JSON: realizing data transmission and parsing Dec 17, 2023 pm 03:06 PM

The combination of golangWebSocket and JSON: realizing data transmission and parsing In modern Web development, real-time data transmission is becoming more and more important. WebSocket is a protocol used to achieve two-way communication. Unlike the traditional HTTP request-response model, WebSocket allows the server to actively push data to the client. JSON (JavaScriptObjectNotation) is a lightweight format for data exchange that is concise and easy to read.

How to exclude a field from JSON using @Expose annotation in Java? How to exclude a field from JSON using @Expose annotation in Java? Sep 16, 2023 pm 09:49 PM

The Gson@Expose annotation can be used to mark whether a field is exposed (contained or not) for serialization or deserialization. The @Expose annotation can take two parameters, each parameter is a boolean value and can take the value true or false. In order for GSON to react to the @Expose annotation, we have to create a Gson instance using the GsonBuilder class and need to call the excludeFieldsWithoutExposeAnnotation() method, which configures Gson to exclude all fields without Expose annotation from serialization or deserialization. Syntax publicGsonBuilderexclud

What is the difference between MySQL5.7 and MySQL8.0? What is the difference between MySQL5.7 and MySQL8.0? Feb 19, 2024 am 11:21 AM

MySQL5.7 and MySQL8.0 are two different MySQL database versions. There are some main differences between them: Performance improvements: MySQL8.0 has some performance improvements compared to MySQL5.7. These include better query optimizers, more efficient query execution plan generation, better indexing algorithms and parallel queries, etc. These improvements can improve query performance and overall system performance. JSON support: MySQL 8.0 introduces native support for JSON data type, including storage, query and indexing of JSON data. This makes processing and manipulating JSON data in MySQL more convenient and efficient. Transaction features: MySQL8.0 introduces some new transaction features, such as atomic
