If NDBM support is used, NDBM will actually create
|
|
<filename>filename.dir</filename> and <filename>filename.pag</filename>
|
|
files. GDBM only uses one file, as does the internal flat-file support,
|
|
and Berkeley DB creates a <filename>filename.db</filename> file.
|
|
</para>
|
|
<para>
|
|
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
|
|
<filename>.lck</filename> 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
|
|
<ulink url="&url.gdbm;">GNU's GDBM</ulink>.
