2.PHP如何记录错误和发送错误

Jun 23, 2016 pm 01:31 PM

1. 将错误记录到指定的文件中,配置过程如下
* 1). log_errors=on
* 2). error_log=/tmp/php_error.log
1.使用error_log()函数记录错误日志
error_log(‘要记录的错误信息!’);

header('content-type:text/html; charset=utf-8');//开启所有的错误报告error_reporting(-1);//设置时区ini_set('date.timezone', 'PRC');//禁用页面显示错误ini_set('display_errors', 0);//开启日志记录功能ini_set('log_errors', 1);//设置错误日志保存的位置ini_set('error_log', '/tmp/custom_error.log');//忽略重复的错误ini_set('ignore_repeated_errors', 'on');//忽略重复的错误来源ini_set('ignore_repeated_source', 'on');error_log('我要把你记录到我的自定义错误日志中'.date('Y-m-d H:i:s', time()));trigger_error('trigger_error-----我要把你记录到我的系统错误日志中'.date('Y-m-d H:i:s', time()), E_USER_NOTICE);settype($var, 'king');

2.将错误记录到系统日志中
* 1.ini_set('error_log', 'syslog');常用

方法一//开启所有的错误报告error_reporting(-1);//禁用页面显示错误ini_set('display_errors', 0);//开启日志记录功能ini_set('log_errors', 1);//设置错误日志保存的位置------(系统日志)ini_set('error_log', 'syslog');//忽略重复的错误ini_set('ignore_repeated_errors', 'on');//忽略重复的错误来源ini_set('ignore_repeated_source', 'on');// error_log('error_log-----我要把你记录到我的系统错误日志中'.date('Y-m-d H:i:s', time()));trigger_error('trigger_error-----我要把你记录到我的系统错误日志中'.date('Y-m-d H:i:s', time()), E_USER_NOTICE);// settype($var, 'king');方法二//====================出于安全问题不用===========================//打开到系统日志的链接openlog('PHP5.6.0', LOG_PID, LOG_SYSLOG);syslog(LOG_ERR, 'this is a test syslog'.date('Y-m-d H:i:s', time()));closelog();
Copy after login

2.将错误日志通过邮件发送
* 1.error_log('msg', 1, mail_addr); 第二个参数设置为1
** bool error_log ( string $message [, int $message_type = 0 [, string $destination [, string $extra_headers ]]] )

message应该被记录的错误信息。message_type设置错误应该发送到何处。可能的信息类型有以下几个:error_log() 日志类型0   message 发送到 PHP 的系统日志,使用 操作系统的日志机制或者一个文件,取决于 error_log 指令设置了什么。 这是个默认的选项。1   message 发送到参数 destination 设置的邮件地址。 第四个参数 extra_headers 只有在这个类型里才会被用到。2   不再是一个选项。3   message 被发送到位置为 destination 的文件里。 字符 message 不会默认被当做新的一行。4   message 直接发送到 SAPI 的日志处理程序中。destination目标。它的含义描述于以上,由 message_type 参数所决定。extra_headers额外的头。当 message_type 设置为 1 的时候使用。 该信息类型使用了 mail() 的同一个内置函数。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

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.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

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.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
