Final answer:
In response to the question, a basic HTML form and PHP script example is provided that allows a user to submit a name and receive a greeting. PHP's built-in htmlspecialchars function is used for security.
Step-by-step explanation:
The question you are asking is related to the creation of a simple HTML and PHP application. Programming, especially with HTML and PHP, involves writing code that browsers and servers can interpret. Below is a basic example of an HTML form that sends data to a PHP script which then displays the submitted information.
HTML Code
Create a file named 'form.html':
<!DOCTYPE html>
<html>
<head>
<title>Simple HTML Form</title>
</head>
<body>
<form action="submit.php" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
PHP Code
Create a file named 'submit.php':
<?php
if(isset($_POST['name'])) {
$name = htmlspecialchars($_POST['name']);
echo "Hello, {$name}!";
}
?>
This example shows a simple form where users can enter their name. When they submit the form, the PHP script will safely retrieve the name using the $_POST array and display a greeting. It is important to use the htmlspecialchars function to prevent security issues like cross-site scripting (XSS).
