How to find #hashtags in strings using Laravel 4.1?

Question

I am currently trying to filter through an Input string to find the single hashtags that a user wants to be displayed with his photo. However, I am currently getting inserts in

Answer 1

Try this:

$str = $hashtag_string;

       preg_match_all('/#(\w+)/', $str, $matches);


       foreach ($matches[1] as $hashtag_name) {

       $hashtag =   Hashtag::firstOrCreate(array('hashtag' => $hashtag_name));

                                    }

You could then, in this foreach loop, connect those hashtags to a post (or in your case a photo) or sth.
