What are some best practices for displaying different levels of importance (0 to 2) as strings in PHP after saving?

When displaying different levels of importance (0 to 2) as strings in PHP after saving, it's important to use a switch statement to map the numeric values to their corresponding string representations. This allows for easy maintenance and readability of the code. Additionally, it's a good practice to define constants for the different importance levels to avoid magic numbers in the code. 

// Define constants for importance levels
define('LOW', 0);
define('MEDIUM', 1);
define('HIGH', 2);

// Function to convert importance level to string
function getImportanceString($level) {
    switch ($level) {
        case LOW:
            return 'Low';
        case MEDIUM:
            return 'Medium';
        case HIGH:
            return 'High';
        default:
            return 'Unknown';
    }
}

// Example usage
$importanceLevel = 1;
$importanceString = getImportanceString($importanceLevel);
echo "Importance level: $importanceString";
