Class Details

This class represents a configuaration reader capable of reading options from database tables.

A configuration table looks like this for MySQL

 CREATE TABLE config (
  id      INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
  cnfset  CHAR(32)     NOT NULL DEFAULT "default",
  sect    CHAR(32)     NOT NULL DEFAULT "default",
  opt     CHAR(32)     NOT NULL DEFAULT "",
  opt_t   ENUM("scalar", "array") NOT NULL,
  val     VARCHAR(255) NOT NULL,
  val_t   ENUM("string", "integer", "double", "boolean") NOT NULL
 );

and for PostgreSQL

 CREATE TABLE testconfig (
  id      SERIAL  PRIMARY KEY,
  cnfset  VARCHAR(32)  NOT NULL DEFAULT 'default',
  sect    VARCHAR(32)  NOT NULL DEFAULT 'default',
  opt     VARCHAR(32)  NOT NULL DEFAULT '',
  opt_t   VARCHAR(8)   NOT NULL,
  val     VARCHAR(255) NOT NULL,
  val_t   VARCHAR(8)   NOT NULL
 );

Note: Arrays must be stored one row each value.
