PHP Luminova: Log Levels

The Luminova LogLevel class defines a set of constants representing various logging levels, following standard practices for logging severity. These constants provide a consistent way to categorize and manage log messages based on their importance and urgency.

• Standardized Log Levels: Includes levels like EMERGENCY, ALERT, ERROR, and DEBUG for comprehensive logging.
• Custom Levels: Adds additional levels, such as PHP, EXCEPTION and METRICS, are for other application use cases.

Use Cases

• Categorize log messages by severity for better organization.
• Integrate into logging systems to ensure consistent handling of log levels.
• Extend or filter logs based on specific levels, such as debugging or performance metrics.

Example

Logging message:

$logger->log(LogLevel::CRITICAL, 'This is a critical error');

Validating log level:

if (LogLevel::has('critical')) {
    echo "Log level 'critical' is valid.";
} else {
    echo "Log level not recognized.";
}
