What is a CMS (Content Management System) and how does it relate to PHP development?

A Content Management System (CMS) is a software application that allows users to create, manage, and modify digital content without needing specialized technical knowledge. PHP is commonly used in the development of CMS platforms due to its flexibility, scalability, and ability to interact with databases. PHP can be used to create dynamic websites, manage user permissions, and customize the appearance and functionality of a CMS.

<?php
// Sample PHP code for creating a simple CMS page
$pageTitle = "Home Page";
$content = "Welcome to our website!";
$dateCreated = date("Y-m-d");

// Connect to database and insert page data
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "cms";

$conn = new mysqli($servername, $username, $password, $dbname);

$sql = "INSERT INTO pages (title, content, date_created) VALUES ('$pageTitle', '$content', '$dateCreated')";

if ($conn->query($sql) === TRUE) {
    echo "Page created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
