有个疑问，你找个gbk的json串是如何生成的？
具体转换方法，很简单，把字符串转换为utf8编码，在调用json_decode既可。
具体原因可以查看博客
http://www.bo56.com/%E5%9C%A8php%E4%B8%AD%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8json_decode%E8%A7%A3%E6%9E%90gbk%E7%BC%96%E7%A0%81%E7%9A%84json%E5%AD%97%E7%AC%A6%E4%B8%B2/
这是直接从网页用curl抓取的，要是自己用json_ecode生成我也知道很简单
现在问题就是这个用gbk编码的数据已经存在了，怎样去解码
<?php$json = '"信海龙"'; //一个符合json格式的gbk编码串var_dump(json_decode($str)); //输出NULL$str = mb_convert_encoding($json, "utf8", "gbk");var_dump(json_decode($str)); //输出 string(9) "信海龙"?>
为什么转换为utf8编码后，就可以正常使用json_decode，参加日志
http://www.bo56.com/%E5%9C%A8php%E4%B8%AD%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8json_decode%E8%A7%A3%E6%9E%90gbk%E7%BC%96%E7%A0%81%E7%9A%84json%E5%AD%97%E7%AC%A6%E4%B8%B2/
现在问题就是这个用gbk编码的数据已经存在了，怎样去解码
那你就把数据用utf-8 编码就可以了
$s=你的json串print_r(json_decode(iconv('gbk','utf-8',$s),true)); 晕个，写过无数种转换了，一直都没成功，现在发现原来是淘宝U站的问题，一放到外站，随便怎么写都ok能正确解码的，晕死
还是谢谢各位

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?
Apr 17, 2025 am 12:25 AM
PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
