As someone who's just turned the corner with php - I now can't see how I did without it.
 
I wholeheartedly recommend learning at least some basics.
 
Tutorials are ok, but you're best maybe choosing a project that requires php. For example, I just created a CMS for a company - the company administrators can add information to the system, and then clients/affiliates can log in and view data relating to their cases etc...
 
It's something that I've developed as I've gone along and learned a LOT in the process. I have had some support from here too - Andy with jQuery and Steve with the php.
 
As a result, I know now that I can offer clients more, and that the design of my sites in future will be quicker i.e. using include files for footers etc.
