If you need web hosting for PHP then your online business will be continued, congratulations!
HTML only supported web hosting is fine if your either beginner or there is no reason for you to use PHP scripting in your desired webpage.
Web hosting for php significantly increases the versatility of the site. You go from basic web design and move up to adding various professional extras to your site.
For example, when I first started out in online business all was well until I learned more about what I could actually do. Adding refer friends involved in one of ny first websites was a major headache. It took me a lot of valuable time to figure out why it would not work.
Only then did I realize that my hosting package that I was on was not supporting PHP. So upgrade was needed. It was very simple to do this. Just the thing to pay a little more for my hosting plan!
When it was set up in WA free to continue with the plans I had to increase the amount of things I could do on my site.
A membership site was something I was looking and I need web hosting for PHP to do this. As I said before adding a refer a friend script needs me to have web hosting for PHP.
You see if you are in the right direction with online business then its an absolute necessity for you to get your web hosting for PHP .. But do not just choose any web hosting for PHP. You have to look in the PHP version you require and what the latest supported PHP is available.
Its not good to use software that uses PHP 4 when your web hosting for PHP is running PHP 5
