XXVI. DBM Functions [deprecated]
Wstęp
These functions allow you to store records stored in a dbm-style database. This type of database (supported by the Berkeley DB, GDBM, and some system libraries, as well as a built-in flatfile library) stores key/value pairs (as opposed to the full-blown records supported by relational databases).
Notatka: DBM support is deprecated and you are encouraged to use the Database (dbm-style) abstraction layer functions instead.
Notatka: This extension has been removed from PHP and is no longer available as of PHP 5.0.0.

option. In
addition you must ensure support
