How to start creating a php script, that will be installed on many servers?

Can I change an existing htm page to php?

• I started making a website with Dreamweaver, and so far all my pages are with .htm extension. In my future plans I want to put some interactive features on some of the EXISTING pages, that require PHP. ( I already installed XAMPP). The question is, can I change these pages to .php extension from now just to be ready? Is this even possible? And what if I start creating pages from now on with php even if they don't require PHP coding? Sorry, I am really new in this.

• Answer:

  Yes you can change your .html pages to .php if you wish. All you will need to do is make sure your files are stored in the 'htdocs' folder within xampp on your C drive. Just because the page has a .php extension, it doesn't necessarily mean you need PHP code within your page. I too have recently started using .php extensions as opposed to .html and I just use the; <?php include "header.php"; ?> This 'header.php' file includes the header part of my website that I want to include on every page I create, it also keeps the code nice and neat and saves a lot of time too as you don't have to keep editing the code every time you make a change, you only have to make a change to the 'header.php' file and it's done for all of my pages. So yeah, just change the extensions but always be sure to have XAMPP running. Hope this helps.
