# 前言在使用`PHP`渲染页面页面的时候,如果程序处理的时间特别久,超过配置文件(php.ini)设置的超时时间,就会出现如下提示:>Maximum execution time of 30 seconds exceeded例如:导入大量数据到数据库中;请求资源时间过长……# 问题PHP程序超时发生错误提示怎么办?# 方法* 直接修改配置文件(php.ini)[超时]```#默认的最大执行时间是30s,可根据自己的需求做修改#如果是0,即永不过期max_execution_time = 30;```* 间接修改配置信息[超时]在php执行文件中加入如下代码:``` phpset_time_limit(0);```* 刷新输出缓冲[内存超限] 1. 在循环当中做延迟执行:加入函数`sleep(time)` 2. 输出缓冲:同时使用`ob_flush()`和`flush()`函数将数据发送到浏览器``` php<?phpfor ($i=0; $i < 10000; $i++) { echo "hello ".printf('%05s',$i).'<br/>'; ob_flush(); flush();}```

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
