In the provided PHP code snippet, what are the potential risks or drawbacks of using the saferstring function for data manipulation before executing the update query?

The potential risks of using the saferstring function for data manipulation before executing the update query include the possibility of introducing SQL injection vulnerabilities if the function does not properly sanitize the input data. To solve this issue, it is recommended to use prepared statements with parameterized queries to prevent SQL injection attacks. 

// Fix: Using prepared statements with parameterized queries to prevent SQL injection

// Assuming $conn is the database connection

// Input data
$name = saferstring($_POST['name']);
$email = saferstring($_POST['email']);
$id = $_POST['id'];

// Prepare the update query
$stmt = $conn->prepare("UPDATE users SET name = ?, email = ? WHERE id = ?");
$stmt->bind_param("ssi", $name, $email, $id);

// Execute the update query
$stmt->execute();

// Close the statement and connection
$stmt->close();
$conn->close();
