Currently, keeping QQ online automatically is very popular. Recently, I came across a piece of PHP code written by an expert to achieve QQ auto-login and wanted to share it with everyone.
Here is the code:
```php
```
Note: 1. Requires support for the curl module; 2. After logging in, your friends will see you as online; 3. It's unclear how to log out.
Implementations in other languages are similar. Friends who are interested can try developing it themselves.
