Why not try learning in a logical sequence what to do for web developemnt?
Yeah you don't wanna learn it, but you want ot make a website right?
If you want to do web development, you should learn PHP, and also:
MySQL (SQL in general but MySQL is popular),
html of course,
CSS,
Javascript,
database theory, on how to optimize a database and how to build it right.
regular expressions,
Jquery,
security measures (this is a constant learning playground)
maybe Java...
As you can see, there are a lot of things to learn than PHP to build a website.
Tweaking an existing code you do not understand in order to create a site, will not do.
You just make something to cover your needs FOR NOW.
Asking for someone else to do it, will not do again.
Are you using a CMS by any chance? Or did you used copy- paste code?
If you want to make jist a simple page, why not learning Wordpress?
There are lots of step by step videos out there that can teach you that.
Wordpress has a ready framework that helps you build a site, tweak it and maintain it easier.
Of course tweaking Wordpress code is another story. You fall on the first option.
It is easier to work with it though, instead of learning software engineering.
