read a file from local harddisk

HI... sorry to interrupt again... I have another ridiculous question... I have a text file in my machine... and a php-file in my host (such as host.sk etc..) I want to use my php-file to access my text file in my machine directly... I used fopen, and fread stuff... but didn't work.... Btw, can somebody help my with this.... I want to know how to access my local file in Windows and Linux remotely... or it can risk some security problem ??? Please... help me... ---DuFronte---   http://binusti2002.net.tc
