I was curious how I could tell if a file was a directory... so I found on http://www.hmug.org/man/2/stat.html the following information about the mode bits: #define S_IFMT 0170000 /* type of file */ #define S_IFIFO 0010000 /* named pipe (fifo) */ #define S_IFCHR 0020000 /* character special */ #define S_IFDIR 0040000 /* directory */ #define S_IFBLK 0060000 /* block special */ #define S_IFREG 0100000 /* regular */ #define S_IFLNK 0120000 /* symbolic link */ #define S_IFSOCK 0140000 /* socket */ #define S_IFWHT 0160000 /* whiteout */ #define S_ISUID 0004000 /* set user id on execution */ #define S_ISGID 0002000 /* set group id on execution */ #define S_ISVTX 0001000 /* save swapped text even after use */ #define S_IRUSR 0000400 /* read permission, owner */ #define S_IWUSR 0000200 /* write permission, owner */ #define S_IXUSR 0000100 /* execute/search permission, owner */ Note that these numbers are in octal format. Then, to check to see if the file is a directory, after calling fstat, I do: if ($fstats[mode] & 040000) ... this must be a directory ---- Manual Page -- http://www.php.net/manual/en/function.stat.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+34919 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+34919&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+34919&report=yes
