How can special characters be properly stored in a database when using Ajax to update data in PHP?

Special characters can be properly stored in a database when using Ajax to update data in PHP by encoding the data before sending it via Ajax, and then decoding it before storing it in the database. This ensures that special characters are handled correctly and do not cause any issues with the database. 

// Encode the data before sending it via Ajax
$data = json_encode($_POST['data']);

// Decode the data before storing it in the database
$data = json_decode($data);

// Insert the data into the database
$query = "INSERT INTO table_name (column_name) VALUES ('$data')";
mysqli_query($connection, $query);
