Save result of Var_dump to variable and use it

Hi,

 

sorry I am new to php but I am a bit stuck. 
I am using below code to check a license through a webservice. The result of var_dump is bool(true).
How can I save the True and use it to for example show an image or a text? Let's say if it's true show something when false do nothing

function checkLicense($key, $url = null) {
	static $wsdl = 'X';

	if ($url == null) {
		$url = $_SERVER['HTTP_HOST'];
	}
	$clientOptions = array(
			'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP,
			//'trace'=> 1, // when the service b0rks, enable the tracing, for easier debugging
	);
	$client = new SoapClient($wsdl, $clientOptions);
	$params = array(
			'LicenseKey' => $key,
			'URL' => $url,
	);
	$checkLicenseResponse = $client->CheckLicense($params);
	return !empty($checkLicenseResponse->IsValid) && $checkLicenseResponse->IsValid === true;
}

$licensekey = Mage::getStoreConfig('SDOCP_options/module/enable_serial'); 
$url = '';
var_dump(checkLicense($licensekey, $url));

instead of var_dump,

$result = checkLicense($licensekey, $url);

will store the value in the variable $result.
