Yes, that's a good point. In some situations it may be better to use
str_replace, substring, or similar functions.

For me, the best way to learn was just trying to apply regex in
projects I was already doing. At first, I spent a lot of time
debugging, until I eventually started getting the hang of them (now one
of my favorite features in a language). Tutorials that demonstrated
with strings like "aaabc" often made it harder for me to grasp.
However, http://regularexpressions.info is a pretty good reference
