What are the advantages and disadvantages of using a pre-built CMS versus creating a custom backend in PHP for small projects?

When deciding between using a pre-built CMS or creating a custom backend in PHP for small projects, it's important to consider the advantages and disadvantages of each option. A pre-built CMS like WordPress or Joomla can save time and effort by providing ready-made solutions for content management, user authentication, and other common features. However, using a pre-built CMS may limit flexibility and customization options compared to creating a custom backend in PHP. Custom backends allow for greater control over the functionality and design of the project but require more time and expertise to develop.

// Example of creating a custom backend in PHP for a small project

<?php

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Perform SQL queries and handle data processing here

// Close the database connection
$conn->close();

?>
