Works through DOS, not through Apache

Can anyone tell me why the following code won't work when I call it through Apache, but it DOES work when I do it in a Command Prompt? It gives me 0 when I run it through Apache. I'm have PHP set up to run as CGI. PHP 4.0.6 w/ latest 4.0.7-dev snapshot on top. What I'm going to end up doing is copying the files from an UNC path over to the local server (running PHP), but I can't get anything to work with UNC paths when called through Apache, not even a system call to "move". But everything always works in a Command Prompt. If you can think of another way I could do this on demand, I would greatly appreciate it, as this is driving me crazy! <? if ($dir = @opendir("//workstation//test")) { while($file = readdir($dir)) { if ($file !="." && $file !="..") $arFiles[] = $file; } } ?> File_Array Count: <? $asize = sizeof($arFiles); print $asize; ?> Thanks, Shawn Sellars
