Php 需要数组键来匹配另一个数组键

使用我的表格设置（我知道这不是正确的设置），如果

分支.id

位于

用户.notify

字段中，将

分包

数据分组到一封电子邮件中发送给用户的最佳方式是什么

我的当前代码如下，但我无法获得匹配的分支名称（

if（$user\u value->branch===$key）

），我只是觉得有更好的方法来完成我需要做的事情

MySQL（表的设置不是最好的，但目前它是最好的）

PHP

$users结果（分支仅列出一个分支，即使notify有多个分支，也可以）

$branch_用户结果

我不明白你的问题是什么。您已经知道您的表设置不正确。那么你到底期望什么呢？我试图集中精力去理解你的需求，但这并不是那么容易……如果你说出你想要实现的目标，也许会更容易。即使是您正在寻找的$user\u value->branch所需的输出也有如下名称（branch 1，branch 3）。您的密钥是（分支1、分支3）。所以它们不匹配。@phaberest我已经在底部添加了所需的结果。我知道这让人困惑，但修理桌子不是一个选项：（@MartavisGriffin那只是我帖子中的一个错误。我不明白你的问题是什么。你已经知道你的表格设置不正确。那么你到底期望什么呢？我正试图集中精力了解你的需求，但这并不是那么容易……如果你说出你想要实现的目标，也许会更容易。即使只是想要的输出t您正在查找$user\u value->branch的名称类似于（branch 1，branch 3）。您的键是（branch\u 1，branch\u 3）。因此它们将不匹配。@phaberest我已将所需结果添加到底部。我知道这很混乱，但修复表不是一个选项：（@MartavisGriffin这只是我帖子中的一个错误
