PHP, an abbreviation for Hypertext Preprocessor, has emerged as one of the most popular and versatile server-side scripting languages. Its simplicity, flexibility, and wide range of functionalities have made it a go-to choice for web developers worldwide. In this article, we will delve into the English website source code, providing an in-depth analysis of the PHP language and its role in creating dynamic and interactive web pages.
1、Understanding PHP:
PHP is an open-source scripting language designed for web development. It is primarily used for server-side scripting, enabling developers to create dynamic web pages and applications. PHP code is executed on the server before being sent to the client's browser, resulting in dynamic content generation.
1、1 PHP Syntax:
PHP syntax is similar to C, Java, and Perl, making it easy for developers with a background in these languages to learn and adapt. PHP code is enclosed within tags, allowing it to be seamlessly integrated into HTML, XML, and other markup languages.
1、2 PHP File Extension:
PHP files are typically saved with a .php extension, indicating that they contain PHP code. These files can be executed on servers that have PHP installed, such as Apache, Nginx, and Microsoft IIS.
2、The English Website Source Code:
Let's take a closer look at an English website source code and understand how PHP plays a vital role in its functionality.
2、1 HTML Structure:

An English website source code begins with an HTML structure, defining the overall layout and content. This includes the doctype declaration, HTML, head, and body tags.
<!DOCTYPE html>
<html>
<head>
<title>English Website</title>
</head>
<body>
<!-- PHP code will be inserted here -->
</body>
</html>2、2 PHP Integration:
PHP code is integrated into the HTML structure using tags. This allows developers to dynamically generate content based on user input, database queries, and other conditions.
<!DOCTYPE html>
<html>
<head>
<title>English Website</title>
</head>
<body>
<?php
// PHP code goes here
echo "Welcome to the English Website!";
?>
</body>
</html>2、3 Variables and Data Manipulation:
PHP variables are declared using the dollar sign ($) followed by the variable name. These variables can store data, such as user input, database results, and other dynamic content.
<?php $name = "John Doe"; $age = 25; echo "Hello, " . $name . "! You are " . $age . " years old."; ?>
2、4 Control Structures:
PHP provides various control structures, such as if-else, switch-case, and loops, enabling developers to create conditional and iterative processes.
<?php
if ($age > 18) {
echo "You are an adult.";
} else {
echo "You are a minor.";
}
?>2、5 Database Integration:
PHP offers seamless integration with databases, such as MySQL, allowing developers to retrieve, store, and manipulate data.
<?php
// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");
// Fetch data from the database
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);
// Display the fetched data
while ($row = mysqli_fetch_assoc($result)) {
echo $row['name'] . "<br>";
}
// Close the database connection
mysqli_close($connection);
?>3、Benefits of PHP:
