在PHP结果数组生成不正确的结果？

Question

这是我的桌子＆amp;我的查询是

$qrs=$select questionID,answer,count(answer) as answer_cnt 
  from `sg_finished_surveys` 
  WHERE  answer='$q' and questionID ='$questionID';   

和

foreach($qrs as $qrow)
 {  
  ['<?=$qrow['answer']?>',<?=$qrow['answer_cnt']?> ],       
 }

结果只会获得最后一个值
