Question

I am working on a csv import option on my php page. Is there any way to allow the user to upload a csv for processing and then destroy the file when it is complete? I have seen plenty of tutorials for uploading files, but none seem to mention something like this.

Answer 1

When you upload a file to PHP it’s stored in a temporary location, you can move it from there to a working directory, do your processing and then remove it.

$working_file = "/temporary/file";
move_uploaded_file($_FILES["file"]["tmp_name"], $working_file);
... // Do your processing on $working_file
unlink($working_file);

All you have to do is unlink() it when you’ve finished processing to delete it.
