How to convert HTML to PHP source code
For many beginners, HTML is their first programming language. However, the functionality of HTML is limited. It can only provide static pages and cannot directly access the database or dynamically generate content. This is where the PHP language comes in. In this article, we will learn how to convert HTML to PHP source code.
- Understand the PHP language and server environment
First of all, you need to understand PHP and the server environment. PHP is a server-side scripting language, and all PHP code is executed on the server rather than running in the user's browser. Therefore, to run PHP code, there must be a server environment capable of running PHP.
For example, you can use XAMPP to create a local server environment, which allows you to run PHP on your local computer and view the results in a browser. Note that if you want to run PHP publicly on a website, you need to use a web server.
- Create PHP file
Now you need to create a .php file on your web server, which will be your PHP script file. In this file, you can embed code using PHP tags, which are defined using .
For example, if you want to output "Hello World!" in PHP, you can write like this:
<?php echo 'Hello World!'; ?>
- Add HTML code to PHP file
Once you have created the PHP file, you can add HTML code to convert the HTML page into PHP source code. You can use PHP's echo statement to output your HTML code.
For example, the following is a basic HTML page:
<!doctype html> <html> <head> <title>My Page</title> </head> <body> <h1>Welcome to my page</h1> <p>This is my first PHP page.</p> </body> </html>
To convert this HTML page to PHP, copy all the HTML code into your PHP file and use the echo statement to output they.
<?php echo '<!doctype html>'; echo '<html>'; echo '<head>'; echo '<title>My Page</title>'; echo '</head>'; echo '<body>'; echo '<h1>Welcome to my page</h1>'; echo '<p>This is my first PHP page.</p>'; echo '</body>'; echo '</html>'; ?>
When you run your PHP file, the exact same page as your HTML file will be output.
- Using PHP functions and variables
Now, you have successfully converted HTML code into PHP source code, but doing so is only a small part of the PHP language. By using PHP functions and variables, you can add many powerful features to your pages.
For example, if you wanted to dynamically display the current date and time, you could use PHP's date function:
<?php
echo '<p>Today is '.date('l jS F Y').'</p>';
echo '<p>The time is '.date('g:i a').'</p>';
?>The result would be something similar to the following:
<p>Today is Monday 23rd March 2020</p> <p>The time is 2:00 pm</p>
Also Variables can be added to PHP code to dynamically generate content. For example, you can create a variable named $name and use the echo statement to output it:
<?php $name = 'John'; echo '<p>Welcome, '.$name.'!</p>'; ?>
The output is as follows:
<p>Welcome, John!</p>
- Conclusion
Converting HTML to PHP source code is not difficult. Just add the required HTML code in the PHP file and apply PHP tags and functions. Once you become familiar with PHP's basic syntax and functionality, you will be able to create web applications with truly dynamic content and powerful functionality.
