Php Laravel将CSV数据解析为数组/对象：添加了重复/不正确的记录
该函数的思想是上载CSV，将其与数据库中的多个点进行比较，并根据比较方式将每一行推入单独的数组。这将帮助我确定在上传干净的副本以提交到数据库之前需要进行哪些手动输入工作（如果有）。由于某些原因，CSV行被多次检查并放入错误的数组中。下面是我的代码，包括期望的结果。以下是基本概念： 上载CSV文件并使用rx#/pharmacy和doctor/patient创建唯一变量 对照数据库检查rx#/pharmacy，查看是否存在精确匹配。如果是，则将行添加到Php Laravel将CSV数据解析为数组/对象：添加了重复/不正确的记录,php,laravel,Php,Laravel,该函数的思想是上载CSV，将其与数据库中的多个点进行比较，并根据比较方式将每一行推入单独的数组。这将帮助我确定在上传干净的副本以提交到数据库之前需要进行哪些手动输入工作（如果有）。由于某些原因，CSV行被多次检查并放入错误的数组中。下面是我的代码，包括期望的结果。以下是基本概念： 上载CSV文件并使用rx#/pharmacy和doctor/patient创建唯一变量 对照数据库检查rx#/pharmacy，查看是否存在精确匹配。如果是，则将行添加到现有_记录数组中。如果rx存在，但药房错误，则将

对于处方数据库中的每个条目，您都要检查名称是否匹配，并相应地添加到fail/success，这可能就是重复项的来源
有很多方法可以解决这个问题，但是如果稍微有点难看的话，最简单的方法是使用循环通过每个记录进行比较，就像你现在做的那样，但是不是每次你发现匹配添加一个记录，每次你发现不匹配添加一个失败的记录，在找到匹配时，将布尔值设置为true和break，并超过循环的末尾，进行简单的if检查，查看匹配查找布尔值是否为true，如果为true，则将记录添加到success，如果不是，则将记录添加到fail列表
希望这是有意义的。请您也展示一个CSV文件的示例。有足够的例子来涵盖所有可能的差异rows@RiggsFolly没问题，谢谢！我走了布尔路线，在foreach循环之后移动了第二个if/else。伟大的横向思维！
