How can PHP be used to efficiently read form data through a loop without repetitive code?

To efficiently read form data through a loop without repetitive code in PHP, you can use an associative array to store the form field names as keys and then loop through this array to extract the values. This approach reduces redundancy in the code and makes it easier to manage form data.

// Define an associative array to store form field names
$form_fields = ['name', 'email', 'message'];

// Loop through the form fields array to extract values
$form_data = [];
foreach($form_fields as $field) {
    $form_data[$field] = isset($_POST[$field]) ? $_POST[$field] : '';
}

// Access form data using the keys in the associative array
$name = $form_data['name'];
$email = $form_data['email'];
$message = $form_data['message'];
