To generate a short URL, we can directly use a function to generate a unique address with a length of 5-6 characters, but what we need to do is to directly use it to make a static jump. I will introduce it to you below.
Generate short URL program
The code is as follows
代码如下 |
复制代码 |
function code62($x){
$show='';
while($x>0){
$s=$x % 62;
if ($s>35){
$s=chr($s+61);
}elseif($s>9&&$s<=35){
$s=chr($s+55);
}
$show.=$s;
$x=floor($x/62);
}
return $show;
}
function shorturl($url){
$url=crc32($url);
$result=sprintf("%u",$url);
return code62($result);
}

RewriteEngine On
RewriteBase /
RewriteRule ^/(.*)$ link.php?url=[L]

The job generated in this way is like htt:/z.cn/abcfc, but if we want to achieve access, we need to configure a pseudo-static in your apache or iis, as follows

How to convert
http://z.cn/link.php?url=http://www.bKjia.c0m
Shrunk to
http://z.cn/zHEYrvV
This place needs to use url rewriting. According to this example, it can be rewritten like this:
