What best practices should be followed when naming form fields in PHP to avoid conflicts?

When naming form fields in PHP, it is important to follow best practices to avoid conflicts with existing variables or functions in your code. One common practice is to use a naming convention that includes a unique prefix or namespace for your form fields. This helps to differentiate them from other variables and functions in your codebase. Additionally, you should avoid using reserved keywords or special characters in your form field names to prevent any potential conflicts. 

// Example of using a unique prefix for form field names
$form_prefix = 'my_form_';

// Define form fields with unique names
$form_field1 = $_POST[$form_prefix . 'field1'];
$form_field2 = $_POST[$form_prefix . 'field2'];
