I've got a quick question:

I'm opening up a file, giving everything in the file to the variable $content, and now what I want to do is delete everything before and after the instance of a string. For example, if my file contained:

blahblahblahblahblahblah+_john+_blahblahblahblahblahblah, I want to go through the file and substitute everything before and after the +_ with white space, so that $content would only consist of "john".

Is this something I can do with substitute?
