0. Forget everything you know about php and programming in general really.
1. Make a simple web page in an html file
2. rename it to .php
3. then throw in some <?php ?> tags
4. Look up [include](https://www.php.net/manual/en/function.include.php) and not much more
5. PROFIT
At least that's how I remember writing php in high school.
