在我们的项目当中，如果需要更好传播我们的活动链接，但是链接太长1来是不美观，2来是太过于“笨重”，例如拼多多，淘宝联盟，他们的推广链接都是有短链接的，还有新浪微博。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html

但是，这些始终都是别人的，我们调用别人的API进行生成，不稳定，所以可以自己做一个，注册一个稍微短一些的域名就行。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html

使用方法文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html

1、访问api.php?url=长链接，即可生成短链接，例如返回JSON文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html

{"code":"0","url":"http://xxx.cn/Hp8R"}文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html

2、新建.htaccess，把上面规则复制进去，保存文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html

3、新建index.php，把上面代码拷贝进去，配置好数据库。访问http://xxx.cn/Hp8R，就会自动跳转到你的长链接php生成短网址/短链接原理和用法实例文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/42933.html
