Php simulates the implementation method of online number statistics of aspApplication objects. application object _ PHP Tutorial

Php imitates the implementation method of online number statistics for the aspApplication object, which is an application object. Php imitates the implementation method of online number statistics for the aspApplication object. the application object example in this article describes the implementation method of php imitating the online number statistics of the aspApplication object. I will share it with you for php to simulate the implementation of asp Application object online number statistics, application object

This example describes how php simulates asp Application object online count statistics. Share it with you for your reference. The specific implementation method is as follows:

The code is as follows:

/*
Usage:
Application ('key', 'value'); // set key = value
$ Value = application ('key'); // Obtain the key value
*/

Function application ()
{
$ Args = func_get_args (); // Obtain the input parameter
If (count ($ args)> 2 | count ($ args) <1) return;
$ Ssid = session_id (); // save the current session_id
Session_write_close (); // ends the current session
Ob_start (); // disable the global session from sending the header.
Session_id ("xxx"); // register global session_id
Session_start (); // enable global session
$ Key = $ args [0];
If (count ($ args) = 2) // if the second parameter exists, it indicates that the global session is written.
{
$ Re = ($ _ session [$ key] = $ args [1]);
}
Else // if there is only one parameter, the value corresponding to this parameter is returned
{
$ Re = $ _ session [$ key];
}
Session_write_close (); // end the global session
Session_id ($ ssid); // re-register the non-global session interrupted above
Session_start (); // restart
Ob_end_clean (); // discard some header output due to session_start.
Return $ re;
}
