Converting an HTML to a PHP file - php

I designed an order form using pForm. It is an HTML/CSS automated code. But now I think, it should be a PHP file because I need to add PHP code into it.
If I add just when the HTML file starts and at the end, probably HTML will stop working.
How to change this file to a PHP file and also preserve its present look and feel?

You can literally change the file extension to ".php".
Then you can pepper your new php file with php code like so:
<html>
<head></head>
<body>
<?php
echo 'Hello world!<br />' ;
?>
</body>
</html>

just change the extension to php
and you can add any PHP code using tags. this doesnt need to be in the top but in any place of the code :)

What gets executed first? Is it script inside php tag or HTML?

I have a file with .php extension.
I am following a tutorial and it has both and in a same file.
So the file looks something like:
<?php
?>
<!DOCTYPE html>
<html>
</html>
I was wondering which gets executed first?
BTW, this is a sidetrack to this problem.
This particular file has to do with preventing CSRF attack.
Inside HTML, there is a PHP snippet that looks like
<?php Token::generate() ?>
in one of the hidden text fields.
I am not sure why he put both front end and back end in one file.
Is this the necessity to do CSRF prevention?
Thanks in advance.
PHP gets executed on the server, output of this execution is a HTML code.
The browser takes the HTML code and displays it.
I think the execution is based on the order written in the file. Since PHP is on the top, PHP gets executed first.

How to embed this php code in html?

I decided to build a booking calendar and embed it to my website. But I don't know how to include it in the html file. I tried the <?php ?> tag but it doesn't display at all. I looked around and found this htaccess file thing. How do I generate it? Is it a way to use my php code without this?
Here is what included in my big html file (I did not include other html here)
<!DOCTYPE html>
<hmtl>
<head>
</head>
<body>
<?php
include 'calendar.php';
$calendar = new Calendar();
echo $calendar->show();
?>
</body>
</html>
I used sublime text edit and there is no "color" on the key words meaning it is not recognizing the php tag.
Place the php code of the calendar in a file and save it as say, calendar.php and then add the following line in the pages where you want the calendar to appear in:
<?php include("calendar.php"); ?>
N.B. Make sure to replace the file extension of all your html files with .php extension instead of the .html extension.
For example: index.html should be index.php

how do you put php into HTML5

I just want to know how to put PHP into HTML5 ?
You can easily use contractions as < ?=$variable?> inside html.
There is no any difference of using php tags between html versions
First name you file to index.php instead if index.html
then you can write php wherever you want in that file..
<html>
<?php
write your php code here
?>
</html>
First you need Web server.
You can embed php code in whatever place you want inside html document, to make it run it should be delimited with <?php your_php_code ?> and save document with .php extension.

Extra output in for php in html hello world file

I'm creating a LAMP stack and just started learning PHP. I'm having trouble with my Hello World program. On my server I have a file called index.html. This is the contents of that file (which is basically copy pasted from an online guide):
<html>
<title>HTML with PHP</title>
<body>
<h1>My Example</h1>
<?php
echo '<p>Hello World</p>';
?>
<b>Here is some more HTML</b>
</body>
</html>
When opened on a web browser, I expect my output to look something like this:
My Example
Hello World
Here is some more HTML
Instead, it looks like this:
My Example
Hello World
'; ?> Here is some more HTML
Why is that extra "'; ?>" there? I'm probably making a simple mistake. I've tried accessing index.html on chrome, firefox, and safari, same result each time.
PHP does not work in HTML files, try renaming it to index.php
Apart from that the code is fine (maybe some best practices like separating HTML and PHP, but you'll get to that later)
The reason you don't see the whole PHP code on your screen is because the browser is trying to parse the element <?php *** ?> as if it where valid HTML (like <span>). If you check the html-source, you will see all of your code.
As someone in the comments below mentioned, there are ways to make PHP work in HTML. You should not do this, unless you are very aware of what you are doing. It is not a default setting and it should stay that way. If you should be able to use PHP in HTML files, .phpfiles would not have to exist.
When you expand your knowledge, you will start separating HTML files from PHP files and make PHP include templates. Two separate files for two separate goals
Rename the file to index.php.
In addition to this, the PHP code must be interpreted by a WEB SERVER(Apache in your case).
For example(if you are using XAMPP on Windows), and your php file is present in the webcontent directory of your server's document root(htdocs), then type the following in your browser
http://localhost/htdocs/webcontent/index.php.
Like others said, you must rename index.html to index.php, but if you must use index.html, put the line below into your .htaccess file, so you can process .html files as .php.
AddType application/x-httpd-php .html

how to write a php embed code that calls another php in a html page

How to write a PHP code (using public id) that can embed into HTML file (abc.html) when we open that HTML file that has to call another PHP file(there we can insert stats of that file into database).
if i cannot do this in php, is there any other way except renaming html file extension to php extension
Do you mean this?
<html>
...
<body>
<?php echo "test"; ?>
</body>
</html>
or
using exec('php foo.php'); to call another php file?
or
including another php file using
include 'foo.php';
require 'anotherfoo.php';
EDIT:
Or you can use ajax to call a .php file to the abc.html file.
$.ajax({
type: 'POST',
url: 'foo.php',
data: 'username=myuser&id=123456',
success: function(result) {
/* do something with result here */
}
});
You need to have the jquery library which can be downloaded here.
If I understood you correctly, you're wanting to use the PHP include function. You may also want to check PHP's include_once function depending on what you're doing.
You will need to make sure the "HTML" page is actually a PHP page. If your page is already written and exists as HTML and not PHP, you will need sufficient privileges to edit the MIME types and associate .html (or whatever file extention you're using) with PHP processes on the server side. Otherwise you will need to recreate the page as a PHP page using the .php file extension.
For example you may have code like this in the initial file:
<!DOCTYPE html>
<HTML>
<HEAD>
<TITLE>My Web page title</TITLE>
</HEAD>
<BODY>
<p>Welcome to my website</p>
<?php include('this_page.php'); ?>
</BODY>
</HTML>
This will call the this_page.php file and allow it to execute any scripts within it.
I hope this helps you.
You cannot embed PHP into an web page, PHP is a server side scripting language, which means it is only executed on the server. The user does not even know whether you are using PHP (except for the .php extension, but that means nothing.)
You can however call a PHP script from another PHP script, e.g.
exec('php script.php');
include(other_file.php), include_once(other_file.php), require(other_file.php), require_once(other_file.php) ...
or
use an iframe or exec(other_file.php)
Within your HTML you could use a tag such as an image or script to call your php script. This could be useful if you want your PHP to do something simple such as to increment a counter in a database.
<img src="/path/to/script.php" alt="" />
This is trivial as long as you don't want the executing PHP to return anything visible within the page. If you use an image tag, after you've finished with whatever processing you are doing, it might be best to have your PHP return an image of some sort - but it could be as trivial as a 1px by 1px transparent gif.
$im = file_get_contents('/path/to/your/image/transparent.gif');
header('content-type: image/gif');
echo $im;
