Re: What is wrong with this code?

  Shouldn't this be:

array(self::INTEGRITY_CONST_UNIQUE => 'uniqueness constraint violated');

...

    public static function getMessage($ec)
    {
        $text = '';
        if (array_key_exists($ec, Pg_Error::$errors))
        {
            $text = Pg_Error::$errors[$ec];
        }

        return $text;
    }

... } ? Calling it, the array_key_exists call always returns false: $this->assertEquals('uniqueness constraint violated', Pg_Error::getMessage(Pg_Error::INTEGRITY_CONST_UNIQUE)); and I can't see what I've done wrong :(
