HTML is the skeleton of a website page but if you want to create, for example, a blog, you will probably feel tired to create 100 blocs with content, one by one.

PHP is a langage created to dynamicly create HTML, it cans create 100 blog post block in a split of second by communicating with a database containing your blog articles informations.

HTML manage the viewing part when PHP handle informations to write inside HTML.

With HTML you will need to write :
