I want to retrieve all hashtags from a tweet using a PHP function.
I know someone asked a similar question here, but there is no hint how exactly to implement this in PHP. Since I'm not very familiar with regular expressions, don't know how to write a function that returns an array of all hashtags in a tweet.
So how do I do this, using the following regular expression:
$tweet = "this has a #hashtag a #badhash-tag and a #goodhash_tag"; preg_match_all("/(#\w+)/", $tweet, $matches); var_dump( $matches );
*Dashes are illegal chars for hashtags, underscores are allowed.
