How to delete files on win98

[catchupvijay]

Hi ..

I am running PHP 4.2 on win98.Having trouble deleting files.
Have tried using delete(){not supported},unlink{not supported},system("del t.txt"){not working}...

Can anybody tell me how to delete files.Also the function need to be comkpatible with Unix,as this code will be runned on unix PHP.

Thanx

system("command /c del ". $myfile);
