Answer 1

$tripid=$_REQUEST['tripid'];
$sql="SELECT * FROM tripdetails WHERE trip_id='".$tripid."'";
$trpresult=mysqli_query($connect,$sql);
  if(mysqli_num_rows($trpresult)==1)
    {
      $trpdetails=mysqli_fetch_assoc($trpresult);
    }
 $trpstartdate = substr_replace($trpdetails['trip_start_date'],T,11,0);

 $string = preg_replace('/\s+/', '', $trpstartdate);

This is Html part
