What are some best practices for error handling and troubleshooting when working with summed data in PHP?

Issue: When working with summed data in PHP, it is important to handle errors and troubleshoot any issues that may arise to ensure accurate calculations and prevent unexpected behavior. Best practices for error handling and troubleshooting include validating input data, checking for division by zero, using try-catch blocks to catch exceptions, and logging errors for further analysis. 

// Example code snippet for error handling and troubleshooting with summed data in PHP

try {
    // Validate input data
    $num1 = 10;
    $num2 = 0;

    if ($num2 == 0) {
        throw new Exception("Division by zero error");
    }

    // Perform sum calculation
    $sum = $num1 + $num2;

    // Output result
    echo "Sum: " . $sum;
} catch (Exception $e) {
    // Log error message
    error_log("Error: " . $e->getMessage());
}
