如何正确运用PHP json_encode函数进行中文转换_PHP
JSON
json_encode 和 json_decode
这两个函数的具体用法 网上有很多相关的文章 ,本文主要介绍 用json_encode 时中文无法转换的解决方案,本文假设文件所用的编码为gb2312;
先写出所需的数组
$json = array ( 0 => array ( 'id' => '13', 'name' => '乒乓球', ), 1 => array ( 'id' => '17', 'name' => '篮球', ) ) ?> |
如果直接用PHP json_encode函数
echo json_encode($json); ?> |
结果为:
[{"id":"13","name":null} ,{"id":"13","name":null}] ?> |
可以看到汉字没有被转义都为null,这是因为json仅仅转义encoding编码(类似于:%B0%AE),故上面语句应该先转换编码
foreach ($ajax as $key=>$val) { $ajax[$key]['name'] = urlencode($val['name']); } echo json_encode($json); ?> |
客户端js代码
用上面的代码js会报错 说编码不符合标准
原因是因为js 中decodeURI 仅仅支持utf8 转码。所以 ,PHP json_encode函数的代码应该为下面的代码
foreach ($ajax as $key=>$val) { $ajax[$key]['name'] = urlencode(iconv('gb2312', 'utf-8',$val['name'])); } echo json_encode($json); ?> |
以上就是使用PHP json_encode函数在实际操作中出现问题的解决方法。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
