What are the implications of using different case conventions for variable names in PHP form processing?

Using different case conventions for variable names in PHP form processing can lead to errors and confusion in your code. It is important to maintain consistency in variable naming conventions to ensure clarity and readability. To solve this issue, you can standardize your variable names by choosing a specific case convention (such as camelCase or snake_case) and sticking to it throughout your code. 

// Example of standardizing variable names using camelCase convention
$firstName = $_POST['first_name'];
$lastName = $_POST['last_name'];
$email = $_POST['email'];
