Php imitates the implementation method of online number statistics of aspApplication objects. Php imitating aspApplication object online number statistics implementation method this article mainly introduces php imitating asp Application object online number statistics implementation method, through a simple custom php imitating asp Application object online number statistics implementation method

This article mainly introduces php's implementation method of imitating asp Application object's online number of people Statistics. Using a simple user-defined function, this function has some reference value, for more information, see

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;
}
