[BB Code] Fast creation a link to a thread or post

[TDCT]

I have an idea of generating a link to a posted thread with its own thread's name.

For example, my thread's id is 10. Then I use a tag named "thread" to create the link. I type:
10

The result is:
<a href="showthread.php?t=10>Thread's name goes here</a>

I wonder how to use php coding in BB Code to get the thread's name. Can anyone help me or develop this idea?

Thanks for your consideration!

Can anyone help me with a full solution or just a small tip to deal with a part of this issue?

Thanks a million!
