The first argument is the full-path filename of the DBM file to
|
|
be opened and the second is the file open mode which is one of
|
|
"r", "n", "c" or "w" for read-only, new (implies read-write, and
|
|
most likely will truncate an already-existing database of the
|
|
same name), create (implies read-write, and will not truncate an
|
|
already-existing database of the same name) and read-write
|
|
respectively.
|
|
</para>
|
|
<para>
|
|
Returns an identifier to be passed to the other DBM functions on
|
|
success, or &false; on failure.

</para>
|
|
<para>
|
|
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. 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>.
