  8. // For each hashtag, strip all characters but alpha numeric
  9. if(!empty($matchedHashtags[0])) {
  10. foreach($matchedHashtags[0] as $match) {
  11. $hashtag .= preg_replace("/[^a-z0-9]+/i", "", $match).',';

  15. return rtrim($hashtag, ',');
  16. }
  17.  
  18. //convert text to clickable links
  19. function convert_clickable_links($message)
  20. {
  21. $parsedMessage = preg_replace(array('/(?i)\b((?:https?:\/\/|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:\'".,<>?«»“”‘’]))/', '/(^|[^a-z0-9_])@([a-z0-9_]+)/i', '/(^|[^a-z0-9_])#([a-z0-9_]+)/i'), array('<a href="$1" target="_blank">$1</a>', '$1<a href="">@$2</a>', '$1<a target="_blank" href="http://codexpresslab.blogspot.com.ng/search?q=$2">#$2</a>'), $message);
