我dump了一个数组，显示如下：

array(9) {  [0] => array(6) {    ["que_content"] => string(11) "11111111111"    ["que_id"] => string(1) "1"    ["ops_qid"] => string(1) "1"    ["ops_contentoid"] => string(1) "A"    ["ops_content"] => string(14) "aaaaaaa1111111"    ["ops_count"] => string(1) "3"  }  [1] => array(6) {    ["que_content"] => string(11) "11111111111"    ["que_id"] => string(1) "1"    ["ops_qid"] => string(1) "1"    ["ops_contentoid"] => string(1) "B"    ["ops_content"] => string(10) "bbbbbbbbbb"    ["ops_count"] => string(1) "1"  }  [2] => array(6) {    ["que_content"] => string(11) "11111111111"    ["que_id"] => string(1) "1"    ["ops_qid"] => string(1) "1"    ["ops_contentoid"] => string(1) "C"    ["ops_content"] => string(8) "cccccccc"    ["ops_count"] => string(1) "1"  }  [3] => array(6) {    ["que_content"] => string(9) "222222222"    ["que_id"] => string(1) "2"    ["ops_qid"] => string(1) "2"    ["ops_contentoid"] => string(1) "D"    ["ops_content"] => string(9) "ddddddddd"    ["ops_count"] => string(1) "3"  }  [4] => array(6) {    ["que_content"] => string(9) "222222222"    ["que_id"] => string(1) "2"    ["ops_qid"] => string(1) "2"    ["ops_contentoid"] => string(2) "EF"    ["ops_content"] => string(12) "efe2efef2fef"    ["ops_count"] => string(1) "1"  }  [5] => array(6) {    ["que_content"] => string(9) "222222222"    ["que_id"] => string(1) "2"    ["ops_qid"] => string(1) "2"    ["ops_contentoid"] => string(1) "F"    ["ops_content"] => string(14) "fff32fffffffff"    ["ops_count"] => string(1) "1"  }  [6] => array(6) {    ["que_content"] => string(9) "333333333"    ["que_id"] => string(1) "3"    ["ops_qid"] => string(1) "3"    ["ops_contentoid"] => string(2) "GG"    ["ops_content"] => string(13) "ggg323ggggggg"    ["ops_count"] => string(1) "1"  }  [7] => array(6) {    ["que_content"] => string(9) "333333333"    ["que_id"] => string(1) "3"    ["ops_qid"] => string(1) "3"    ["ops_contentoid"] => string(1) "H"    ["ops_content"] => string(10) "hhh5h5h5h5"    ["ops_count"] => string(1) "2"  }  [8] => array(6) {    ["que_content"] => string(9) "333333333"    ["que_id"] => string(1) "3"    ["ops_qid"] => string(1) "3"    ["ops_contentoid"] => string(1) "J"    ["ops_content"] => string(8) "j8j8j8j8"    ["ops_count"] => string(1) "2"  }}

我想输出的时候这样子输出，应该要怎样做？

问题：11111111111选项：A    内容：aaaaaaa1111111选项：B    内容：bbbbbbbbbb选项：C    内容：cccccccc问题：222222222选项：D    内容：ddddddddd选项：EF    内容：efe2efef2fef选项：F    内容：fff32fffffffff问题：333333333选项：GG    内容：ggg323ggggggg选项：H    内容：hhh5h5h5h5选项：J    内容：j8j8j8j8

回复讨论(解决方案)

刚刚弄出来你看看：

foreach($a as $v){  if($qid!=$v['ops_qid']){	echo '问题:'.$v['que_content']."<br>";	$qid=$v['ops_qid'];  }else{    echo '选项：'.$v['ops_contentoid'].'     内容'.$v['ops_content']."<br>";  }}

貌似要稍加改动：
代码如下：

foreach($a as $v){  if($qid!=$v['ops_qid']){    echo '问题:'.$v['que_content']."<br>";    echo '选项：'.$v['ops_contentoid'].'     内容'.$v['ops_content']."<br>";    $qid=$v['ops_qid'];  }else{    echo '选项：'.$v['ops_contentoid'].'     内容'.$v['ops_content']."<br>";  }}

if($qid!=$v['ops_qid'])

$qid是指什么啊？

$qid 是一个临时变量，用于存放上一轮的 ops_qid。这样就可以检查到是否是新问题了

to nowphp
为什么要改成 #2 的样子，将 #1 的 else 删掉不就可以了吗？
