ช่วยแนะนำเรื่องการตรวจข้อสอบหน่อยได้มั๊ยค่ะ ติดมานานพอควรแล้วค่ะ

	$sql2="SELECT * FROM  choice  WHERE  IDquestion='".$IDquestion[test][IDquestion]."'";
						$IDchoice[question]= mysql_query( $sql2 , $link );
							while ( $choice[q]=mysql_fetch_array( $IDchoice[question] ) )
			{	
			echo  $i." ".$choice[q][question];
									$w=$choice[q] [answer]; 
									$x=$choice[q] [choice1]; 
									$y=$choice[q] [choice2]; 
									$z=$choice[q] [choice3]; 
									$arr=array ( $w,$x,$y,$z); 
									shuffle($arr); 
									echo  "$IDQ[6]<br>\n";
										echo  "<input type=radio name='choice[$c]' value='$arr[0]' > $arr[0]<br>\n";
										echo  "<input type=radio name='choice[$c]' value='$arr[1]' > $arr[1]<br>\n";
										echo  "<input type=radio name='choice[$c]'  value='$arr[2]'> $arr[2]<br>\n";
										echo  "<input type=radio name='choice[$c]' value='$arr[3]'> $arr[3]<br>\n\n";
