Is it best practice to perform parameter validations in individual scripts rather than in a centralized loop for all cases?

It is generally considered best practice to perform parameter validations in individual scripts rather than in a centralized loop for all cases. This approach allows for more specific and targeted validation logic tailored to each script's requirements, improving code readability and maintainability. 

// Individual script performing parameter validation
function validateParameters($param1, $param2) {
    if (!is_numeric($param1) || $param1 < 0) {
        throw new InvalidArgumentException('Parameter 1 must be a non-negative number');
    }
    
    if (empty($param2)) {
        throw new InvalidArgumentException('Parameter 2 cannot be empty');
    }
    
    // Additional validation logic for other parameters
}

// Example usage
$param1 = 10;
$param2 = 'example';

try {
    validateParameters($param1, $param2);
    // Proceed with script logic if parameters are valid
} catch (InvalidArgumentException $e) {
    echo 'Error: ' . $e->getMessage();
}
