//checking if data has been entered
if( isset( $_POST['data'] ) && !empty( $_POST['data'] ) )
{
$data = $_POST['data'];

exit();
}
//setting up mysql details
$sql_server = 'localhost';
$sql_user = 'user';
$sql_pwd = 'password';
$sql_db = 'database';
//connecting to sql database
$myslqi = new mysqli( $sql_server, $sql_user, $sql_pwd, $sql_db ) or die( $mysqli->error );
//inserting details into table
$insert = $mysqli->query( "INSERT INTO table ( `data` ) VALUE ( '$data' )" );

$mysqli->close;
