        'region'    => 'us-east-2',
        'version'   => 'latest',
    'credentials' => $credentials,

$compareFaceResults= $rekognitionClient->compareFaces([
    'SimilarityThreshold' => 80,
    'SourceImage' => [
        'Bytes' => file_get_contents("test.jpg")
    ],

 $FaceMatchesResult = $compareFaceResults['FaceMatches'];
 $SimilarityResult =  $FaceMatchesResult['Similarity']; //Here You will get similarity
 $sourceImageFace = $compareFaceResults['SourceImageFace'];
 $sourceConfidence = $sourceImageFace['Confidence']; //Here You will get confidence of the picture
