Are there any security considerations to keep in mind when copying and rewriting database entries in PHP?

When copying and rewriting database entries in PHP, it is important to sanitize user input to prevent SQL injection attacks. You can achieve this by using prepared statements with parameterized queries to safely insert or update data in the database. 

// Assuming $conn is your database connection

// Sanitize user input
$newData = filter_var($_POST['data'], FILTER_SANITIZE_STRING);

// Prepare a statement with a parameterized query
$stmt = $conn->prepare("UPDATE table SET column = ? WHERE id = ?");
$stmt->bind_param("si", $newData, $id);

// Execute the statement
$stmt->execute();
$stmt->close();
