Are there any security concerns related to processing SVG files in PHP, and what measures can be taken to mitigate these risks?

Processing SVG files in PHP can pose security risks as SVG files can contain malicious code that could be executed on the server. To mitigate these risks, it is important to sanitize and validate SVG files before processing them. One way to do this is by using a library like DOMDocument to parse and validate the SVG file before rendering it. 

// Load the SVG file using DOMDocument
$doc = new DOMDocument();
$doc->load('path/to/file.svg');

// Validate the SVG file
if ($doc->validate()) {
    // Process the SVG file
    // Your code here
} else {
    // Invalid SVG file
    echo 'Invalid SVG file';
}
