What best practices should be followed when naming form elements in PHP for proper data retrieval?

When naming form elements in PHP for proper data retrieval, it is important to use descriptive and unique names for each element. This helps to avoid naming conflicts and ensures that the data can be easily retrieved and processed. It is also recommended to use naming conventions such as camelCase or snake_case for consistency. 

<form method="post" action="process_form.php">
  <input type="text" name="first_name">
  <input type="text" name="last_name">
  <input type="email" name="email">
