What are some efficient ways to manage form data and variables in PHP to avoid confusion and errors?

When managing form data and variables in PHP, it is important to use proper naming conventions and keep track of the data being passed around to avoid confusion and errors. One efficient way to do this is by using associative arrays to store form data and variables in a structured manner. This allows for easy access and manipulation of the data throughout the application. 

// Example of managing form data and variables using associative arrays

// Initialize an empty associative array to store form data
$formData = [];

// Retrieve form data and assign it to the associative array
$formData['username'] = $_POST['username'];
$formData['email'] = $_POST['email'];

// Access and manipulate form data using the associative array
echo "Username: " . $formData['username'];
echo "Email: " . $formData['email'];
