What best practices should be followed when naming form fields and variables to ensure consistency and accuracy in PHP scripts?

When naming form fields and variables in PHP scripts, it is important to follow a consistent naming convention to ensure clarity and accuracy in your code. Use descriptive names that clearly indicate the purpose of the field or variable, and avoid using abbreviations or overly generic names. Additionally, make sure to use camelCase or snake_case formatting to separate words in the name for readability.

// Example of naming form fields and variables following best practices
$userName = $_POST['user_name'];
$userEmail = $_POST['user_email'];
$phoneNumber = $_POST['phone_number'];
