On w98 and w98se it is not possible to change from root directory (eg. c:\) to a relative subdirectory (e.g. windows). There is a delay of about 1 second. The same when accessing file functions (eg. is_dir, filesize) on filenames in the root directory without path (e.g. filesize ("msdos.sys"), no result is returned.

Try this script:

<?PHP
function mychdir ($text, $dir, $works) {
  echo "$text '$dir': "; flush();
  chdir ($dir);
  echo 
    "<font color=". ($works ? "green" : "red").">".
    str_replace ("\\", "/", getcwd ())."</FONT><BR>"; 
  flush ();
}
mychdir ("change to root", "/", true);
mychdir ("change to existing full path", "c:/windows/temp", true);
mychdir ("change to parent", "..", true);
mychdir ("change to relative subdir", "temp", true);
mychdir ("change to parent-parent", "../..", true);
mychdir ("change to root", "/", true);
mychdir ("change to relative subdir from root - does not work (notice the delay)", "windows", false);
?>
