You can do show at this sample class to show how to access/call a static method or attribute from inside a string.

You must store the classname inside a variable, so you can access classelements over this variable and yes you can access static variables and static methods.

self}}::author()}} // don't works
           {${!${''}=static::author()}} // works
           {$self::author()} // works
TEST;
    }
}

$test = 'test'; // this is the trick, put the Classname into a variable

echo "{$test::author()} {$$test::$url}";
echo <<{$test::author()}
