How can debugging techniques be used to identify and resolve PHP code errors related to user registration and activation?

To identify and resolve PHP code errors related to user registration and activation, debugging techniques such as using var_dump() or echo statements can help pinpoint where the issue lies in the code. By checking the input data, database queries, and activation process, developers can identify potential errors and fix them accordingly. 

// Sample code snippet for debugging user registration and activation issues

// Check input data
var_dump($_POST);

// Check database queries
$query = "SELECT * FROM users WHERE email = '$email'";
$result = mysqli_query($conn, $query);
if (!$result) {
    echo "Error: " . mysqli_error($conn);
}

// Check activation process
if ($activation_code == $user['activation_code']) {
    // Activate user account
    $query = "UPDATE users SET activated = 1 WHERE email = '$email'";
    $result = mysqli_query($conn, $query);
    if (!$result) {
        echo "Error: " . mysqli_error($conn);
    }
}
