php数组问题

时间:2021-07-01 10:21:17 帮助过:4人阅读

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']."
"; $qid=$v['ops_qid']; }else{ echo '选项:'.$v['ops_contentoid'].' 内容'.$v['ops_content']."
"; }}

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']."
"; echo '选项:'.$v['ops_contentoid'].' 内容'.$v['ops_content']."
"; $qid=$v['ops_qid']; }else{ echo '选项:'.$v['ops_contentoid'].' 内容'.$v['ops_content']."
"; }}

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?
