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.
<?php
/**
* 短网址
*/
function urlShort($url){
$url= crc32($url);
$result= sprintf("%u", $url);
$sUrl= '';
while($result>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 '<meta charset="utf-8" />';
echo '网址：'.$url.'<br />';
echo '短网址：'.$sUrl;
?>The above introduces a PHP function to generate short URLs, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
