PHP Logger warn is a function used to log warning-level messages into a log file or other output. It is part of the PHP Logger library, which is commonly used to implement logging functionality in PHP applications.
Here are some code examples using PHP Logger warn:
# Example 1: Log a warning message to a file
use Monolog\Logger; use Monolog\Handler\StreamHandler;
// Create a new logger $logger = new Logger('my_logger');
// Add a file handler to the logger $logger->pushHandler(new StreamHandler('path/to/log/file.log', Logger::WARNING));
// Log a warning-level message $logger->warn('Unable to connect to database.');
In this example, we create a new logger instance and add a file handler that writes to a log file. Then, we use the logger's warn() method to log a warning message.
# Example 2: Log a warning message with context
// Log a warning message with additional information $logger->warn('User {username} attempted to access {url}.', array('username' => 'john_doe', 'url' => '/secret/page'));
This example shows how you can use the warn() method to log a warning message along with contextual information. The placeholders in the message string are replaced with values from the context array.
