PHP Introduction
PHP is a server-side scripting language used for web development. It is often used in combination with HTML, CSS, and JavaScript to create dynamic websites and web applications.
Here's a brief example of how PHP can be used to generate HTML:
<!DOCTYPE html>
<html>
<head>
<title>PHP Example</title>
</head>
<body>
<?php
// Define a variable with a string value
$name = "John Doe";
// Use PHP to generate HTML that includes the variable value
echo "<h1>Hello, $name!</h1>";
?>
</body>
</html>
In this example, we define a variable called $name with a string value of "John Doe". We then use PHP's echo function to output an HTML h1 element that includes the variable value. When this code is run on a web server with PHP installed, the output will be an HTML page that says "Hello, John Doe!".
PHP can also be used for more complex tasks, such as database interactions, form processing, and user authentication. It has a wide range of built-in functions and supports many third-party libraries and frameworks, making it a powerful and flexible tool for web development.
