failed to open stream warning

Has anybody had any experience in resolving this kind of issue? Warning: fopen(home/path/temp") failed to open stream: No such file or directory I am trying to write a script to work with GnuPG, but can't get past this basic problem. Everything I try gives me the same warning. Here is the code: $fp = fopen("home/path/temp "w+"); puts($fp, $msg); fclose($fp); any suggestion would be appreciated, Thanks zed
