What considerations should be taken into account when using IDs to customize content in PHP scripts for different web pages?

When using IDs to customize content in PHP scripts for different web pages, it is important to ensure that the IDs are unique and consistent across all pages. This will help in identifying which content should be displayed on each page based on the ID. Additionally, proper error handling should be implemented to handle cases where the ID does not match any content. 

<?php

// Get the ID parameter from the URL
$id = $_GET['id'];

// Define an array of content based on IDs
$content = [
    '1' => 'Content for Page 1',
    '2' => 'Content for Page 2',
    '3' => 'Content for Page 3'
];

// Check if the ID exists in the content array
if (array_key_exists($id, $content)) {
    echo $content[$id];
} else {
    echo 'Content not found';
}

?>
