PHP short URL compressor

The PHP short URL compression program has only one file, only 3KB. It can be used after uploading it to the website. It can also be used in subdirectories. It does not require a database and is easy to use.

How does the program realize that it does not require a database? This program includes four URL compression website interfaces: bit.ly, goo.gl, is.gd, and tinyurl.com. You can choose any one. The default is bit.ly. If your domain name is abc.com, then after inputting a long URL and compressing it, a short URL like http://abc.com/eubUBd will be generated. When this URL is opened, the corresponding URL will be accessed.
http://bit.ly/eubUBd, and then access the compressed long URL. Although it takes one more jump, the speed is still very fast. You can also choose other interfaces.
