How to remove columns from a csv file with PHP?
Question
I know the names of the columns I want to keep in the .csv file, but I am interested in removing all columns in the .csv which I don't recognize. How can php do this?
(The names of the columns are defined in the first row of the file.)

在PHP中，使用fgetcsv（）读取CSV文件，忽略所需的列，然后使用fputcsv（）写回CSV文件。

Look at fgetcsv and fputcsv. Read the contents, write the columns/data back out that you want.
