我需要计算第一列的值。这些 ID 可能存在于我收到的任何给定 .csv 文件中,也可能不存在。因此,我需要循环遍历 .csv 文件,查看第一列,如果不存在,则将其添加到保持数组 ($PWSs) 中,或者如果我已经添加了该保持数组,则增加该保持数组中的计数。
我使用 fgetcsv() 进行第一个循环..这适用于破解文件:
$PWSs = array();
$handle2 = fopen ($uploadfileandpath,"r");
while ($field2array = fgetcsv ($handle2, 130000, ","))
{
// Here is where I would add value or increment $PWSs array
while (?)
{
if ($field2array[0] != ?)
{
// Add or increment
}
}
}
这是实际数据。第一列包含公共供水系统的 ID。我需要数一下它们。
