/**

|
* @file include/config.php
|
|
* @brief Arbitrary configuration storage.
|
|
*
|
|
* @note Please do not store booleans - convert to 0/1 integer values.
|
|
* The get_?config() functions return boolean false for keys that are unset,
|
|
* and this could lead to subtle bugs.
|
|
*
|
|
* Arrays get stored as serialize strings.
|
|
*
|
|
* @todo There are a few places in the code (such as the admin panel) where
|
|
* boolean configurations need to be fixed as of 10/08/2011.
|
|
*
|
|
* - <b>config</b> is used for hub specific configurations. It overrides the
|
|
* configurations from .htconfig file. The storage is of size TEXT.
|
|
* - <b>pconfig</b> is used for channel specific configurations and takes a
|
|
* <i>channel_id</i> as identifier. It stores for example which features are
|
|
* enabled per channel. The storage is of size MEDIUMTEXT.
|
|
* @code{.php} $var = get_pconfig(local_channel(), 'category', 'key');@endcode
|
|
* - <b>xconfig</b> is the same as pconfig, except that it uses <i>xchan</i> as
|
|
* an identifier. This is for example for people who do not have a local account.
|
|
* The storage is of size MEDIUMTEXT.
|
|
* @code{.php}
|
|
* $observer = App::get_observer_hash();
|
|
* if ($observer) {
|
|
* $var = get_xconfig($observer, 'category', 'key');
|
|
* }@endcode
|
|
*
|
|
* - get_config() and set_config() can also be done through the command line tool
|
|
* @ref util/config.md "util/config"
|
|
* - get_pconfig() and set_pconfig() can also be done through the command line tool
|
|
* @ref util/pconfig.md "util/pconfig" and takes a channel_id as first argument.
