Given this code:
<?php
class CallbackClass {
function CallbackFunction() {
// refers to $this
}
function StaticFunction() {
// doesn't refer to $this
}
}
function NonClassFunction() {
}
?>
there appear to be 3 ways to set a callback function in PHP (using register_shutdown_function() as
an example):
1: register_shutdown_function('NonClassFunction');
2: register_shutdown_function(array('CallbackClass', 'StaticFunction'));
3: $o =& new CallbackClass();
register_shutdown_function(array($o, 'CallbackFunction'));
The following may also prove useful:
<?php
class CallbackClass {
function CallbackClass() {
register_shutdown_function(array(&$this, 'CallbackFunction')); // the & is
important
}
function CallbackFunction() {
// refers to $this
}
}
?>
