What are the best practices for structuring PHP code to prevent errors like the one mentioned in the forum thread?

Issue: The error mentioned in the forum thread is likely caused by a lack of proper error handling and validation in the PHP code. To prevent such errors, it is essential to implement robust error handling, input validation, and proper structuring of the code to ensure that unexpected inputs or conditions do not lead to runtime errors. Code snippet: 

// Example of implementing error handling and input validation in PHP code

// Function to divide two numbers with proper error handling
function divide_numbers($numerator, $denominator) {
    if ($denominator == 0) {
        throw new Exception("Division by zero is not allowed.");
    }
    
    return $numerator / $denominator;
}

// Example usage of the divide_numbers function with input validation
try {
    $result = divide_numbers(10, 0);
    echo "Result: " . $result;
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
