PHP - What is a Website?
A website is a collection of web pages or a single web page that is hosted on a web server and can be accessed through the internet. PHP script is used to create dynamic web pages that interact with the user, generate dynamic content and provide customized web applications.
Syntax
The basic syntax to create a webpage using PHP is as follows:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<?php
// PHP code goes here
?>
</body>
</html>
Example
Let's create a simple webpage that displays a message using PHP:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to my website</title>
</head>
<body>
<?php
echo "Hello, welcome to my website!";
?>
</body>
</html>
Output
When you run the above code, the output will be:
Hello, welcome to my website!
Explanation
In the above example, we have created a basic HTML webpage with a title 'Welcome to my website'. The PHP code is embedded inside the body tag using the <?php ?> syntax. The PHP code simply echoes out a message 'Hello, welcome to my website!', which is then displayed in the browser.
