Here's a simple class for URL Validation using RegEx and then cross-references the domain against popular RBL (Realtime Blackhole Lists) servers:

Install:

require 'URLValidation.php';

Usage:

require 'URLValidation.php';
$urlVal = new UrlValidation(); //Create Object Instance

Add a URL as the parameter of the domain() method and check the the return.

$urlArray = ['http://www.bokranzr.com/test.php?test=foo&test=dfdf', 'https://en-gb.facebook.com', 'https://www.google.com'];
foreach ($urlArray as $k=>$v) {

    echo var_dump($urlVal->domain($v)) . ' URL: ' . $v . '
';

}

Output:

bool(false) URL: http://www.bokranzr.com/test.php?test=foo&test=dfdf
bool(true) URL: https://en-gb.facebook.com
bool(true) URL: https://www.google.com

As you can see above, www.bokranzr.com is listed as malicious website via an RBL so the domain was returned as false.
