Bug description: Enable possibility to iterate static or const member in class
with foreach
Description:
------------
I noticed a limitation in (at least) latest version of php.
It's impossible to iterate the const or static member of a
class.
The only possible (but REALY too hard) whould be to use the
reflector propriety.
I don't know if it's a feature to add or a missing
explanation in documentation.
But if it's not supported at all, it should be reported as
a lack of feature in documentation and scheduled for php6 ?
Reproduce code:
---------------
<?php
//The class
class someclass {
//The constant
const someconst = 'somevalue';
//The public static member
public static $somepublicstatic = 'somevalue';
//The protected static member
protected static $someprotectedstatic = 'somevalue';
//The private static member
private static $someprivatestatic = 'somevalue';
//A function to list static or const members
public static function somefunction()
{
//Try to iterate const or static member
foreach(self as $key => $value)
echo "$key = $value\n";
}
}
echo "static function list:\n";
someclass::somefunction();
echo "external list:\n";
foreach(someclass as $key => $value)
echo "$key = $value\n";
?>
Expected result:
----------------
static function list:
someconst = somevalue
somepublicstatic = somevalue
someprotectedstatic = somevalue
someprivatestatic = somevalue
external list:
someconst = somevalue
somepublicstatic = somevalue
Actual result:
--------------
static function list:
