Apache - How can I run a PHP script when opening HTML files?

If you serve static HTML files, you cannot prevent a user to access it without using a programming language like PHP (or e.g. .htaccess). There are however multiple ways to handle your situation:

You could fetch all administrative data from the PHP scripts with AJAX. This means that all your users could theoretically see how your administration is built of (the whole HTML structure without relevant data). Of course, you can create a redirect, if the AJAX call fails, but you are still offering the whole HTML of the administration.
You can store your administration HTML file in the back-end. The user then tries to access the administration and the only thing he gets, is an AJAX call to the back-end. If the call is successful, the HTML is delivered with AJAX to the front-end. This prevents the users to see your administration HTML.
You can use a small PHP snippet on top of every administration page which checks if a user should have access to this page. This prevents the users also to see your administration HTML.
You store the HTML of your administration in an HTML file, also served to the user. Then, you make an initial call to the back-end on page load. In the success case, you make another AJAX call to fetch the administartion HTML. The user could potentially see the administration HTML (if he directly opens the file).
You could use a PHP independent server authentication with .htaccess. .htaccess is an apache server authentication configuration file. You can use it to prevent a user from accessing your site (so, there is no access to the HTML file at all). When trying to access the page, a popup appears and the user has to enter his credentials. It is completely independent from your business logic and the allowed users have to be set in a .htpasswd text file. There is no way to use a modern database-relying user management with .htaccess server authentication. With this solution, you also cannot use an HTML form to log in. I would only recommend this solution for testing purposes and not for a modern website.

If your PHP back-end is solidly built, I would go for solution 1. The user cannot do anything with your HTML, if you are properly checking the user's input on your back-end interface. This means, you serve all the HTML, but do not display it to the user until the data is loaded. You can show a spinner while it is loading. Here is some basic code:

JavaScript (jQuery):

$(document).ready(function() {
    $.ajax({
        url: 'administration.php',
        method: 'GET'
        success: function(response) {
            $('input.username').val(response.username);
            // ( ... )
            $('.administration').fadeIn('fast');
        },
        error: function() {
            window.location.href = 'index.php';
        }
    });
});

HTML:

<body>
    <div class="administration">
        <label>Username 
            <input type="text" class="username" />
        </label>
    </div>
</div>

CSS:

.administration {
    display: none;
}

Execute php script from html

To use ajax, you must first include jquery in the head of your doc, then put the following code below at the end of the body tag (right before </body> tag)

You can then edit the data variable to send your data as $_POST. To access the data this script sends to your php script, you just call the $_POST variables. Ex: to access var2, put in your php script $_POST['var2']. If you use GET instead of post, remember to use $_GET['var2'] in your php script to get that variable.

var data = 'var1=value&var2=value2&var3=value3';

$.ajax({
            type: "POST", //can be POST or GET
            url: "URL_TO_SCRIPT_GOES_HERE.php",
            dataType: "html", //or json
            data: data, //data to send as $_POST to script
            success: function(response) {

                //Once data received, do this
                alert(response);

            },

            error: function(response) {


            }

        });

The database connection line should just be put in the php file. It has nothing to do with the jquery ajax script.

To execute the ajax call, you can just run it how I have here (it will load on page load) or you can put it in a javascript function and call it according to an event:

function my_ajax_call() {
var data = 'var1=value&var2=value2&var3=value3';

$.ajax({
            type: "POST", //can be POST or GET
            url: "URL_TO_SCRIPT_GOES_HERE.php",
            dataType: "html", //or json
            data: data, //data to send as $_POST to script
            success: function(response) {

                //Once data received, do this
                alert(response);

            },

            error: function(response) {


            }

        }); 


}

A onclick button trigger:

<a onclick='my_ajax_call()'>CALL AJAX</a>

Command to run html with php script

Rename file.html to file.php and check.
I think you write PHP and HTML in a single document, and you use only html extension.

How do I run PHP in HTML?

Rename index.html to index.php, and fill it with the following:

<html>
<head></head>
<?php
require('./file.php');
?>
</html>

How do I show / run a PHP file in a browser? As if it was a webpage

You need to download a server, and install it. If you want to go to the trouble, you can get XAMPP, and once it's installed, move the PHP file to the root of your installation (usually c:\xampp\htdocs\ on windows) and then use the url localhost/script.php in your browser.
