3、Basic PHP Syntax:
Understanding the basic syntax of PHP is crucial for creating English websites. Here are some essential concepts:
3、1 PHP Tags:
PHP code is enclosed within special tags:<?php
and?>
. For example:
<?php echo "Hello, World!"; ?>

Variables in PHP are declared using the$
symbol. For example:
<?php $welcome_message = "Welcome to my website!"; echo $welcome_message; ?>
3、3 Control Structures:

,else
,switch
, and loops (for
,while

" - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>"; } } else { echo "0 results"; } $conn->close(); ?>
4、2 Handling User Input:
To create interactive English websites, you need to handle user input. Here's an example of validating user input using PHP:
<?php if ($_SERVER["REQUEST_METHOD"] == "POST") { $name = test_input($_POST["name"]); $email = test_input($_POST["email"]); if (empty($name) || empty($email)) { echo "Name and email are required!"; } else { echo "Name: " . $name . "<br>Email: " . $email; } } function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $data; } ?>
