I understand that private methods can not be called from outside the class. But I
believe that register_tick_function() should disallow registering private or
protected methods or at least there should only be ONE error after leaving the
class scope. Probably PHP should automatically recognize that the class scope was
left, unregister the tick function and issue a notice.
As far as I remember, private methods are fully supported as class autoloaders and
work even when loading a class outside the class scope of the registered private
method. This behavior is somewhat inconsistent.

As the tick function is not called in the class scope it also can't access its private methods.
That's the whole point of private methods. This is also not specific to ticks, its the same
with all private-method callbacks: They will only work if they are invoked from within the class.

Description:
------------
Registering a private method as a tick function leads to two errors on every tick.
Test script:
---------------
<?php
declare(ticks = 1);
class A {
public function __construct() {
register_tick_function(array($this, 'a'));
}
private function a() {
echo 'Called';
}
}
new A;
?>
Expected result:
----------------
CalledCalledCalled
Actual result:
--------------
Called
Warning: Invalid callback A::a, cannot access private method A::a() in
/var/vhosts/pancake/default/register_tick_function.php on line 15
Warning: main(): Unable to call A::a() - function does not exist in
