Depends.

What are your objectives? Why are you learning it? Is PHP your first language? Are you trying to get a job, get general stuff done, or have a specific project in mind? Are you primarily looking at web, text processing, database?

My own thoughts on PHP today is it is a very capable language, and probably as worthy of learning as Python, Ruby, or any of the other mainstream scripting languages - again depends what your objectives are.

In other words - how long is a piece of string? ;)
