$host = "localhost";
$port = "5432";
$dbname = "test";
$user = "postgres";
$password = "postgres";
$connection_string = "host={$host} port={$port} dbname={$dbname} user={$user} password={$password} ";
$dbconn = pg_connect($connection_string);
if(isset($_POST['submit'])&&!empty($_POST['submit'])){
$sql = "insert into public.user(name,email,password,mobno)values('".$_POST['name']."','".$_POST['email']."','".md5($_POST['pwd'])."','".$_POST['mobno']."')";
$ret = pg_query($dbconn, $sql);
if($ret){
echo "Data saved Successfully";
