如何在上传（使用php）之前确定文件的日期？

Question

When I upload a file with PHP, there is the file creation date. How do I grab the date of the original file? I want to store both the upload date AND the date of the original file that the user is uploading.

Answer 1

Use filectime this will return the creation date in windows. in Unix it will give you the last modification data because there is no creation time in Unix.

Use touch for changing the modification time of file.
