PHP Wrapper

The who-hosts-this-php wrapper can help you easily integrate hosting provider detections into any PHP application. This package is open source and hosted on Github.

We recommended installing who-hosts-this-php through Composer.

curl -sS https://getcomposer.org/installer | php

Next, run the Composer command to install the latest stable version:

php composer.phar require whatcms/who-hosts-this-php

Once installed, you can use the WhoHostsThis class to fetch results:

require 'vendor/autoload.php';
$key = 'Your API Key';
$detector = new \WhoHostsThis\WhoHostsThis($key);
$check_url = 'en.wikipedia.org';
$result	 = $detector->CheckUrl($check_url);
print_r($result);

CMS Detection

Fetch WhatCMS.org data with curl, guzzle or your favorite HTTP client.

Curl Example

curl -G https://whatcms.org/APIEndpoint/Detect \
--data-urlencode key="Your-api-key" \
--data-urlencode url="en.wikipedia.org"

Rate Limiting

As we open up our API to more and more usage, the rate limits will help make sure our system will remain stable and available to everyone.

Please note, some API queries will require us to fetch the requested url. If the server for the requested url is slow to respond, our results will also be delayed. We allow up to 20 seconds for responses to complete.
