Emoji for PHP
This library allows the handling and conversion of Emoji in PHP. For background, you might want to read this first. You can download a zipfile of the latest code, which contains a helpful readme file. If you want to browse the code, it's in a public GitHub repo. Example <?php include('emoji.php'); # browser sniffing tells us that a docomo phone # submitted this text $clean_text = emoji_docomo_to_u
