关于PHP的2个数组之间统计数量

Jun 23, 2016 pm 01:18 PM




求救各位大神帮帮!
现在要做的就是,有一个调查问卷,然后要统计别人答题的情况,例如ABC分别多少人选择这样
第一个图是别人提交上来我数据库里面的内容,反序列化后,存在一个数组里面
第二个图是题目和选项
我不知道把数据这样分配在2个数组合不合适?
做统计的话,程序应该怎么写比较合适!
想了好几天。。。


回复讨论(解决方案)

这个在数据库里通过分组查询就可以了
没必要拿出来用 php 做

如果一定想要用 php 数组做,那么请贴出用 var_export 输出的测试数据




数据库中的表里面的问题的设置表格和别人提交上来的表格分别是这样的,不知道怎么下手,还有姓名,留言,电话等这些字段都是不统计的,,,想了好几天总是找不到连接点,,,

你这是 var_dump 的结果!需要改造后才可用
var_export 输出的是 php 代码格式,直接就可用

你好 我能问一下 @$res[$v['name']][$v['value']]++;
这个前面为什么加个@ 吗

还有那个提交的数组,有几个是多选的 ,多选的答案是用逗号分隔开的, 对于那些多选我应该怎么处理比较恰当?

先谢谢你帮我点明了!谢谢!

这就是你的问题了
比如 经管类,建工类,化工、医药类 本来是分属于 您所学的专业是?(多选) 的 经管类、建工类、化工、医药类 子项的,但你把他们联结成了一个串,那就变成一项了。你的再切割成数组,分别统计

foreach($a as $item) {  foreach($item as $v) if(isset($d[$v['name']])) {     foreach(explode(',', [$v['value']]) as $sub)        @$res[$v['name']][$sub]++;  }}

Copy after login
Copy after login



      @$res[$v['name']][$sub]++;

这个变量前面加@ 主要是目的是什么

屏蔽掉 使用了未赋值的变量 这个错误提示

屏蔽掉 使用了未赋值的变量 这个错误提示



 我发现变成这个格式对应的数组之后,是不是没办法在页面用volist标签输出来。。

那你就自己改造了

那你就自己改造了



好 谢谢啦!

那你就自己改造了



你好,我想再请教一下
就是我遍历完了之后,排序都乱了,怎么才能 按进去的顺序,排出来也是按这个顺序呢 

你可先预置 $res

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
