How important is PHP proficiency in attracting visitors to a website?

PHP proficiency is important in attracting visitors to a website because PHP is a widely used server-side scripting language that allows for dynamic and interactive web pages. Websites with well-written PHP code can offer a better user experience, faster loading times, and more functionality, which can attract and retain visitors. Additionally, PHP proficiency is crucial for implementing features such as user authentication, form processing, database integration, and content management systems.

<?php

// Example PHP code snippet for user authentication
$username = "admin";
$password = "password123";

if ($_POST['username'] == $username && $_POST['password'] == $password) {
    echo "Login successful. Welcome, $username!";
} else {
    echo "Invalid username or password. Please try again.";
}

?>
