Does PHP belong to the front-end or back-end?

    PHP is a server-side scripting language, which means it is used for back-end development. The back-end refers to the server-side of an application and everything that communicates between the database and the browser. PHP runs on a web server, and its primary role is to manage and process data from databases and other sources, and then output that data to the front-end of the web application.

    PHP scripts are executed on the server, and the results are sent back to the client as plain HTML. This is different from front-end languages like HTML, CSS, and JavaScript, which run directly in the client's browser.

    Here's a simple example to illustrate PHP's role in back-end development:

    // Connect to a database
    $db = new mysqli("localhost", "username", "password", "database");
    // Check connection
    if ($db->connect_error) {
        die("Connection failed: " . $db->connect_error);
    // Query the database
    $result = $db->query("SELECT * FROM users");
    // Fetch and display results
    while ($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"] . "<br>";
    // Close connection

    In this example, PHP is used to connect to a database, retrieve data, and then output it in a format that can be displayed on the front-end. The front-end, however, does not directly interact with the PHP code. Instead, it receives the final output (typically HTML) which is generated by PHP after it has processed the server-side logic.
