What are the potential pitfalls of using PHP to request and display SVG images located outside the document root?

One potential pitfall of using PHP to request and display SVG images located outside the document root is that it can pose a security risk by allowing access to sensitive files on the server. To mitigate this risk, you can use PHP to read the contents of the SVG file and then output it to the browser, rather than directly linking to the file. 

<?php
// Path to the SVG file
$svgFilePath = '/path/to/svg/file.svg';

// Check if the file exists and is an SVG file
if (file_exists($svgFilePath) && pathinfo($svgFilePath, PATHINFO_EXTENSION) === 'svg') {
    // Set the appropriate header for SVG content
    header('Content-type: image/svg+xml');
    
    // Output the contents of the SVG file
    readfile($svgFilePath);
} else {
    // Handle error if file is not found or not an SVG file
    echo 'SVG file not found';
}
