1 | # English Version:
2 |
3 | # URL-Shorter
4 |
5 | A modern, safe and simple PHP url shorter.
6 |
7 | ## Demo:
8 | [http://bbr.buzz/](http://bbr.buzz/)
9 |
10 | ## Function:
11 | + Use PDO and it's Bindparam to prevent SQL Inject.
12 | + Use Ajax to get the short Code
13 | + Use pure JS to copy the short link
14 | + No more magnificent functions
15 |
16 | ## Installation
17 | 1. Git clone or Download the code and unzip
18 | 2. Add the website in your web server config (Require Apache or Nginx rewrite rules(Similar as Wordpress rewrite rules))
19 | 3. Import the url.sql to your db
20 | 4. Configure the config.php
21 | 5. Finished
22 |
23 | ## Future:
24 | + Redis cache
25 | + Redis control the rate
26 |

29 | # 中文简介:
30 |
31 | # 短链接
32 |
33 | 一个现代、安全且简洁的PHP短链接 (PHP是世界上最好F#fIO#@($)#U)
34 |
35 | ## Demo:
36 | [http://bbr.buzz/](http://bbr.buzz/)
37 |
38 | ## 功能:
39 | + 使用PDO和Bindparam防注入
40 | + 使用Ajax获取短链接(免刷新)
41 | + 使用纯JS复制生成的短链接
42 | + 没有更多功能了
43 |
44 | ## 安装方法:
45 | 1. git clone或者下载代码到网站根目录
46 | 2. 配置好伪静态(Apache直接使用根目录下的.htaccess就可以了，Nginx请自行配置(类似Wordpress的规则))
47 | 3. 导入url.sql到数据库
48 | 4. 配置好配置文件
49 | 5. 完成
50 |
51 | ## 计划中要增加的功能 (计划中，计划中)
52 | + 使用Redis缓存，更快，抗压能力更强
53 | + 使用Redis控制访问速率，抗CC
