Classe: Cache_Container_phplib  - X-Ref

Stores cache data into a database table using PHPLibs DB abstraction.

WARNING: Other systems might or might not support certain datatypes of
the tables shown. As far as I know there's no large binary
type in SQL-92 or SQL-99. Postgres seems to lack any
BLOB or TEXT type, for MS-SQL you could use IMAGE, don't know
about other databases. Please add sugestions for other databases to
the inline docs.

The field 'changed' is used by the garbage collection. Depending on
your databasesystem you might have to subclass fetch() and garbageCollection().

For _MySQL_ you need this DB table:

CREATE TABLE cache (
id          CHAR(32) NOT NULL DEFAULT '',
cachegroup  VARCHAR(127) NOT NULL DEFAULT '',
cachedata   BLOB NOT NULL DEFAULT '',
userdata    VARCHAR(255) NOT NULL DEFAUL '',
expires     INT(9) NOT NULL DEFAULT 0,

changed     TIMESTAMP(14) NOT NULL,

INDEX (expires),
PRIMARY KEY (id, cachegroup)
)
