Bug description:ReflectionMethod::invoke && invokeArgs support static binding...
Description:
------------
I think it'd be useful to be able to set the static binding of a class
method if
it's a static method. Currently you can only set the binding if it's not a
static
method, but my patch (see below) now will allow you to pass a string or an
object
to the ReflectionMethod::invoke and invokeArgs methods allowing you to set
the
static binding of static functions.
The script below will work with the patch in place, but not work with
current
version of PHP because you *must* pass a valid object or null as the first
argument, but if you are wanting it to call a static method my patch will
allow
you to set the Class the static method will run under.
Test script:
---------------
<?php
trait A{
public static function static_method(){
return get_called_class();
}
public function normal_method(){
return get_called_class();
}
public function normal_method_this(){
return get_class($this);
}
}
class B{
}
class C extends B{
use A;
public function test(){
$returns = array();
$returns[] = 'C => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invoke($this);
$returns[] = 'B => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invoke('B');
$returns[] = 'C => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invoke('C');
$returns[] = 'A => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invoke(null);
$returns[] = 'stdClass => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invoke(new
stdClass);
$returns[] = 'C => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invokeArgs($this,
array());
$returns[] = 'B => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invokeArgs('B',
array());
$returns[] = 'C => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invokeArgs('C',
array());
$returns[] = 'A => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('static_method')->invokeArgs(null,
array());
$returns[] = 'C => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invoke($this);
$returns[] = 'stdClass => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invoke(new
stdClass);
$returns[] = 'B => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invoke(new
B());
$returns[] = 'C => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invoke($this);
$returns[] = 'stdClass => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invoke(new
stdClass());
$returns[] = 'B => ' . current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invoke(new
B());
// Normal methods need an object
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invokeArgs($this,
array());
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invoke('B',
array()); // Error
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invoke('B',
array()); // Error
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method')->invoke(null,
array()); // Error
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invokeArgs($this,
array());
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invoke('B',
array()); // Error
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invoke('B',
array()); // Error
//$returns[] = current((new
ReflectionClass('C'))->getTraits())->getMethod('normal_method_this')->invoke(null,
array()); // Error
return $returns;
}
}
$a = new C;
print_r($a->test());
echo "\n";
Expected result:
----------------
Array
(
[0] => C => C
[1] => B => B
[2] => C => C
[3] => A => A
[4] => stdClass => stdClass
[5] => C => C
[6] => B => B
[7] => C => C
[8] => A => A
[9] => C => C
[10] => stdClass => stdClass
[11] => B => B
[12] => C => C
[13] => stdClass => stdClass
[14] => B => B
)
Actual result:
--------------
Currently wont work because you can only pass objects or null as first
parameter
