If NDBM support is used, NDBM will actually create
<TT
CLASS="filename"
>filename.dir</TT
> and <TT
CLASS="filename"
>filename.pag</TT
>
files. GDBM only uses one file, as does the internal flat-file support,
and Berkeley DB creates a <TT
CLASS="filename"
>filename.db</TT
> file.
</P
><P
> Note that PHP does its own file locking in addition to any file locking
that may be done by the DBM library itself. PHP does not delete the
<TT
CLASS="filename"
>.lck</TT
> files it creates. It uses these files simply as
fixed inodes on which to do the file locking. For more information on DBM
files, see your Unix man pages, or obtain
