Retrieve all hashtags from a tweet in a PHP function

Question

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:

#\S*\w 

Answer 1

I created my own solution. It does:

• Finds all hashtags in a string
• Removes duplicate ones
• Sorts hashtags regarding to count of the existence in text

• Supports unicode characters

  function getHashtags($string) {       $hashtags= FALSE;       preg_match_all("/(#\w+)/u", $string, $matches);       if ($matches) {         $hashtagsArray = array_count_values($matches[0]);         $hashtags = array_keys($hashtagsArray);     }     return $hashtags; } 

Output is like this:

(     [0] => #_ƒOllOw_     [1] => #FF     [2] => #neslitükendi     [3] => #F_0_L_L_O_W_     [4] => #takipedeğerdost     [5] => #GönüldenTakipleşiyorum )
