Description:
------------
I wanted to write something like this inside a method.
DEFAULT_CLASS is a string containing a name of an existing class.
The problem is that there is no way to instantiate an object using a class
constant by using "new self::CLASS_CONSTANT";
This will generate a syntax error.
I know that the workaround is to store the value of the class constant into a
variable, but couldn't this be improved somehow?
Test script:
---------------
<?php
class default_class {
function do_nothing() {
}
}
class TheParent {
const DEFAULT_CLASS="default_class";
public function init() {
$c=new self::DEFAULT_CLASS;
}
}
Expected result:
----------------
I would expect to have an object instantiated with the class stored in the
DEFAULT_CLASS constant.
Actual result:
--------------
Produces a syntax error:
syntax error, unexpected T_STRING, expecting T_VARIABLE or '$' in
/some_path/test.php on line 14
