PHP5 Static functions called through __call() that don't exist... yet

Hi all, I am building an assertType object using static functions. What I want to keep away from is the following: <code> public static function assertString($para){ return $answer; }; public static function assertBool($para){ return $answer; }; ... public static function assertArray($para){ return $answer; }; </code> What I would like to do is replace this with the following: <code> if (!class_exists('TypeAssert')) { class TypeAssert {

       private static $types = array(
           'array','bool','float','integer','null','numeric',
           'object','resource','scalar','string'
       );
       public static function __call($method,$arguments) {
           $obj = self::assertStandardTypes($arguments[0]);
           return $obj->$method;
       }
       public static function assertStandardTypes($para) {
           $r = TypeAssert::getTypesObject();
           if (is_array($para))    $r->array = true;
           if (is_bool($para))     $r->bool = true;
           if (is_float($para))    $r->float = true;
           if (is_integer($para))  $r->integer = true;
           if (is_null($para))     $r->null = true;
           if (is_numeric($para))  $r->numeric = true;
           if (is_object($para))   $r->object = true;
           if (is_resource($para)) $r->resource = true;
           if (is_scalar($para))   $r->scalar = true;
           if (is_string($para))   $r->string = true;
           return $r;
       }
       public static function getTypesObject() {
           $obj = (object) '';
           for ($i = 0; $i < count(self::$types); $i++) {
               $obj->{self::$types[$i]} = (bool) false;
           }
           return $obj;
       }

} } echo('<pre>'); echo(TypeAssert::string('test')); echo('</pre>'); </code> I don't think this is possible (see http://marc.info/?l=php-general&m=114558851102060&w=2 ). But I would LIKE for it to work (currently, the above code doesn't). Anybody have any insight on how I might get this to work?
