Everyone is familiar with short URLs, especially applications on Weibo that have made it popular. In fact, it is very simple to implement this function.
Java code
0){ $s= $result%62; if($s>35){ $s= chr($s+61); } elseif($s>9 && $s<=35){ $s= chr($s+ 55); } $sUrl.= $s; $result= floor($result/62); } return $sUrl; } $url = 'www.qttc.net'; $sUrl = urlShort($url); echo ''; echo '网址:'.$url.'
'; echo '短网址:'.$sUrl; ?>
The above result output:
Website: www.qttc.net
Short URL: SwOOy3
The short URL can be stored in the database and make a mapping relationship. Together with nginx rewriting rules, short URL generation, restoration, and jump functions can be realized.
