PHP

If you are learning PHP as your first programming language, then yes the videos will feel quite fast-paced. The videos here are geared towards both beginners and experienced programmers just picking up a different language. You may also want to look at some of the tutorials on w3schools as those are text-based and don't have timers on them. They also go through the content in a little different order.

The main challenge you're probably having is that you are trying to learn all of the concepts of programming while at the same time trying to learn all of the rules of the PHP language. It's a lot to learn at once. You may want to look for some tutorials which cover concepts of programming without actually getting into the details of a specific language. If you can start to write some of the programs as concepts without the details, it may be easier to grasp the concepts. Then you can work on the specific details of a given language.

I'd look on youtube as some people have made animations to try to describe many of the basic concepts of programming.
