In the 5 minutes i took to test it out, it seems that register_shutdown
doesn't seem to like object methods (?)
I did come up with a solution, but it't not really the best way to
do things.... put cRoute_Destructor() into the same file as the
class declarations, so that when you include() the class, you'll
get access to cRoute_Destructor, and to the user, it will appear
to all run smoothly.
// start of cRoute.inc
class cRoute{
function cRoute(){
register_shutdown_function('cRoute_Destructor',$this);
}
function cleanup(){
print "Please call close()";
$this->close();
}
function close(){
//close open sockets, etc.
}
} // End of class
function cRoute_Destructor($x) {
$x->cleanup();
}
// end of cRoute.inc
$test = new cRoute();
exit;
