Is there any way to remove the contents of an file in php, do we have any php command that does that, I know unlink but I do not want to delete the file instead I just want to remove the contents of that file. 
I have an file which I pass while called a getCurrentDBSnap function, it takes in the file from /home/test/incoming folder and populates currentDB table state into the file using fputcsv and puts back file to /home/test/outgoing. 
Currently file stays in incoming folder and when I can call the function getCurrentDBSnap it would take the file and override with latest state of DB into it. 
Q: My question is, is it possible instead of overwriting the file, we can remove the content of file after ever getCurrentDBSnap such that file in incoming folder would be always empty ?
Hope it makes sense :)
