lists "new" as being a reserved keyword. That implies you shouldn't call (static or
non-static) methods "new".

The importance of this bug is just in simplicity: If one wants to have a static method named
"new", that will be creating instances (singletons or
any other controlled process of instantiation), it's more convenient to have a class method
named "new" in the API docs rather than having to type
ClassName::getNewInstance().

Description:
------------
When one defines a class with __callStatic() which under some circumstances
accepts method name of "new", it may not be called. However, with __call(), it may
be called. May be solved using call_user_func(), but that loses the nice syntax.
Personally, I don't get it why "new" is parsed as T_NEW after "Base::" and
not
after $base->.
Test script:
---------------
<?php
class Base {
public static function __callStatic($method, $args) {
if ($method == 'new')
echo 'Base::new() called successfully';
}
public function __call($method, $args) {
if ($method == 'new')
echo '$base->new() called successfully';
}
}
$base = Base::new();
call_user_func(array('Base', 'new');
$base = new Base;
$base->new();
?>
Expected result:
----------------
Base::new() called successfully
Base::new() called successfully
$base->new() called successfully
Actual result:
--------------
Parse error: syntax error, unexpected T_NEW, expecting T_STRING or T_VARIABLE or
'$' in C:\inetpub\wwwroot\test.php on line 14
