Summary: call_user_func_array can't use private methods on the
$this pointer
Status: Bogus
Type: Bug
Package: *General Issues
Operating System: All
PHP Version: 5.2.13
New Comment:
But the originating request came from inside the object. With first
class
functions, you could just pass those around once you were inside the
object (think
python or javascipt). We should emulate the same in PHP.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
Of course you cannot call private instance methods outside of the
object. That's the entire point of private methods.

Description:
------------
I'd like to make a helper library that can use call_user_func outside of
the
object context, but still use private methods (obviously only when
called from
inside the object).
Example attached:
Test script:
---------------
<?php
class A {
private function test1() {
print 'side effect 1';
return false;
}
private function test2() {
print 'side effect 2';
return 'yay';
}
private function test3() {
print 'side effect 3';
return 'nope';
}
public function first() {
return nonempty_lazy(
array(array($this, 'test1')),
array(array($this, 'test2')),
array(array($this, 'test3')));
}
}
function nonempty_lazy() {
$args = func_get_args();
foreach ($args as $arg) {
$cb = array_shift($arg);
$val = call_user_func_array($cb, $arg);
if (!empty($val))
return $val;
}
}
$a = new A;
print $a->first();
Expected result:
----------------
side effect 1side effect 2yay
Actual result:
--------------
Warning: call_user_func_array() expects parameter 1 to be a valid
callback, cannot
access private method A::test1() in /Users/ptarjan/tmp/cufa.php on line
28
Warning: call_user_func_array() expects parameter 1 to be a valid
callback, cannot
access private method A::test2() in /Users/ptarjan/tmp/cufa.php on line

Warning: call_user_func_array() expects parameter 1 to be a valid
