Android สอบถามการใช้งาน Spinner โดยดึงข้อมูล จาก MySQL มาแสดง

<?
	include 'Connect.php';
        
        $strspinnerSelected = $_POST["spinnerSelected"];
	$strSQL = "SELECT * FROM fee 
                    WHERE fee_name= ' ".$strspinnerSelected." ' 
                      ";
	$objQuery = mysql_query($strSQL);
	$intNumField = mysql_num_fields($objQuery);
	$resultArray = array();

	{
		$arrCol = array();
		for($i=0;$i<$intNumField;$i++)
		{
			$arrCol[mysql_field_name($objQuery,$i)] = $obResult[$i];
		}
		array_push($resultArray,$arrCol);
	}
	
	mysql_close($objConnect);
	
	echo json_encode($resultArray);
