Geocode parameter bug on searchTweets()

[x-fran]

This is the code I'm playing with:

        $options = [
            # geocode element has the correct format according to Twitter documentation
            'geocode'=> '53.3242381,-6.3857848,1mi',
            'lang' => 'en',
            'locale' => 'IE',
            'result_type' => 'recent',
            'include_entities' => false,
        ];
        $res = $twitter->searchTweets("Leo Varadkar", $options)->getRawResponse();

I get this error: "geocode" must be of the format "latitude,longitude,radius".

Digging a bit I found bug in the Twitter class line 695.

case 'geocode':
/*line 695*/ if (!substr_count($value, ',') !== 2) {
         throw new Exception\InvalidArgumentException(
        '"geocode" must be of the format "latitude,longitude,radius"'
        );
    }

Should be if (substr_count($value, ',') !== 2) not if (!substr_count($value, ',') !== 2).
Please notice I removed the negation "!" in front of "substr_count" function.
