How to Detect XXE Attacks from Multiple Text Inputs in PHP

If you’re looking for a simple way to protect your web application from XML External Entity (XXE) attacks, you’ve come to the right place. In this brief tutorial, we will demonstrate how you can use an API in PHP to check multiple text inputs for XXE attacks in batch. By integrating this API into your security toolkit, you can shield your XML parser from inadvertently interpreting and executing malicious data.

To use the API, we will need to run this command to install the package:

composer require cloudmersive/cloudmersive_validate_api_client

Now we’re ready to call the function with the following code:

require_once(__DIR__ . '/vendor/autoload.php');

Done! Easy to run, and easy to understand.

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
