It's probably easier just to do it this way...less code to maintain
and no magic (although I like your solution too):
<?php
error_reporting(E_ALL);
class cRoute{
function cRoute(){
//register the shutdown function in case people who use this
//class dont call the appropiate close methods.
register_shutdown_function(array($this, 'cleanup'));
}
function cleanup(){
//cleanup.
trigger_error("Please call close() before the page ends, to
prevent problems close() has been called automatically for you.");
$this->close();
}
function close(){
echo "In close\n";
}
}
$one = new cRoute();
$two = new cRoute();
?>
