PHP logging best practices: Use a logging package (such as Monolog) Define log levels (such as emergency, error, warning) Enrich log messages (including contextual information) Rotate and clean log files Define log handlers (such as file processing Integrated Error and Exception Handling Review and Analyze Logs #In PHP application development, logging is crucial as it provides the insights needed for troubleshooting, performance analysis, and security auditing. Implementing effective logging follows the following best practices:

PHP 日志记录的最佳实践:有效记录和审查问题1. Choose an appropriate logging package

Use a logging package, such as Monolog or PSR-3, to Simplify the logging process. These packages provide predefined log levels, processors, and formatters, saving time on customization.

2. Define the log level

Clearly define the level of events to be logged. Common levels include:

Urgent: A serious problem in which the system cannot be recovered

Error: Indicates a function that cannot be performed properly Warning: A situation that should not occur, But will not interrupt the operation

Information: Events that describe regular operations

    Debug: For debugging purposes
  • 3. Use context rich information Log
  • In addition to the log message, includes additional information about the event, such as:
  • User ID

Request URI Stack Trace

This helps quickly diagnose the problem and understand why it occurred.
  • 4. Rotate and clean logs
  • Log files will grow large over time, so they must be rotated and cleaned regularly. Consider using a log file processor to automate this task at a specified size or time interval.

5. Define the log handler

The log handler determines where the log messages go, such as a file, database, or remote system. Multiple handlers can be configured to meet different needs.

Example:

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

// 创建一个日志器
$logger = new Logger('my_logger');

// 为日志器添加一个文件处理器
$handler = new StreamHandler('my_log.log', Logger::WARNING);
$logger->pushHandler($handler);

// 记录一条日志消息
$logger->warning('Something went wrong!', [
    'user_id' => 123,
    'request_uri' => '/api/v1/users/123',
]);
6. Integrate error and exception handling

By integrating error and exception handling into logging The system can automatically record all errors and exceptions to help quickly identify and solve problems.

7. Review and analyze logs

Regular review and analysis of logs is critical for troubleshooting, performance optimization, and security. Using log analysis tools can simplify this process and help identify trends and patterns.
