forked from extern/egroupware
ae9d87ed97
was broken since some time, because a not closed session kept it from working --> we are now run all callbacks containing "session" it there name, closing session, calling fastcgi_finish_request() and then run rest of the callbacks

/**
|
|
* New written class to create the eGW enviroment AND restore it from a php-session
|
|
*
|
|
* Rewritten by RalfBecker@outdoor-training.de to store the eGW enviroment
|
|
* (egw-object and egw_info-array) in a php-session and restore it from
|
|
* there instead of creating it completly new on each page-request.
|
|
* The enviroment gets now created by the egw-class
|
|
*
|
|
* Use now a php5 getter method to create the usuall subobject on demand, to allow a quicker
|
|
* header include on sites not useing php4-restore.
|
|
* This also makes a lot of application code, like the following, unnecessary:
|
|
* if (!is_object($GLOBALS['egw']->datetime)
|
|
* {
|
|
* $GLOBALS['egw']->datetime = CreateObject('phpgwapi.datetime');
|
|
* }
|
|
* You can now simply use $GLOBALS['egw']->datetime, and the egw class instanciates it for you on demand.
