[Question] do i really need

<What You Should Already Know

Before you continue you should have a basic understanding of the following:

HTML/XHTML
JavaScript>
This was in W3schools (PHP introduction)
 
I learned PHP before I learned javascript. It is not needed whatsoever to learn PHP.
But, especially with in-depth, fancy, or elaborate web sites - javascript is quite helpful.
If you are planning to learn PHP, than you should plan to learn, at the very least, the basics of javascript. But you can do that AFTER you learn PHP.
 
JavaScript isn't necessary at all , JavaScripts are just codes that does its function without reloading , what does that mean, example: when you register on a good website/forum , it tells you if the username is taken or not, does it reload to check? no. That's cause they used javascript.
