These functions allow you to store records stored in a dbm-style
|
|
database. This type of database (supported by the Berkeley DB,
|
|
<ulink url="&url.gdbm;">GDBM</ulink>, 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).

However, dbm support is deprecated and you are encouraged to use the

|
<link linkend="ref.dba">Database (dbm-style) abstraction layer functions</link>
|
|
instead.

To use this functions you have to compile PHP with support for an
|
|
underlying database. See the
