Quick Usage Example

use webignition\SfsResultInterfaces\ResultInterface;

$client = new Cient();

// Query against a single email address
$result = $client->queryEmail('user@example.com');

// $result will be NULL if the HTTP request to query api.stopforumspam.com failed for any reason

if ($result instanceof ResultInterface) {
    $result->getType();                 // 'email', 'emailHash', 'ip' or 'username'
    $result->getFrequency();            // int
    $result->getAppears();              // bool
    $result->getValue();                // the email address, email hash, IP address or username
    $result->getLastSeen()              // \DateTime()|null
    $result->getConfidence()            // float|null
    $result->getDelegatedCountryCode(); // string|null
    $result->getCountryCode();          // string|null
    $result->getAsn();                  // int|null

Understanding and Analysing Results

You probably want to know if a given email address/IP address/username can be trusted to perform an operation within your application.

use webignition\SfsResultAnalyser\Analyser;
use webignition\SfsResultInterfaces\ResultInterface;

// We're assuming that $result is a ResultInterface object.

$analyser = new Analyser();

// Does a given result indicate that the entity is not to be trusted?
$analyser->isUntrustworthy($result));
// returns true or false

// Is a given result's entity trustworthy?
// Return a float between 0 (do not trust) and 1 (probably can be trusted)
$trustworthiness = $analyser->calculateTrustworthiness($result);
