    In PHP, logging is an important aspect of tracking the behavior of your application. There are several ways to print logs in PHP, which include:

    1. Using the error_log() Function:

      • This is a built-in PHP function that sends an error message to the web server's error log, a file, or a remote destination.
      • Example:
        error_log("Error message", 3, "/path/to/your/error.log");
        
      • The '3' here indicates the message should be sent to a log file at the specified path.
    2. Writing to a File Directly:

      • You can also write logs directly to a file using file handling functions like file_put_contents() or fopen().
      • Example:
        file_put_contents('/path/to/your/log.txt', 'Error message', FILE_APPEND);
        
      • This appends the error message to the specified log file.
    3. Using Monolog:

      • Monolog is a popular logging library for PHP.
      • It offers a variety of handlers for logging to files, databases, and other systems.
      • Example:
        use Monolog\Logger;
        use Monolog\Handler\StreamHandler;
        
        $log = new Logger('name');
        $log->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING));
        $log->addWarning('Foo');
        
    4. Using Framework-Specific Logging:

      • If you are using a PHP framework like Laravel or Symfony, they have their own logging facilities which are usually very powerful and easy to use.

    It's important to remember that logging can impact the performance of your application. Therefore, it should be implemented wisely, especially in production environments. Also, ensure sensitive information is not logged, as it can pose security risks.
