安装

composer require ledc/google-code

Usage:

See following example:

<?php $ga = new LedcGoogleCodeGoogleAuthenticator(); $secret = $ga->createSecret(); echo "Secret is: ".$secret."nn"; $qrCodeUrl = $ga->getQRCodeGoogleUrl('Blog', $secret); echo "Google Charts URL for the QR-Code: ".$qrCodeUrl."nn"; $oneCode = $ga->getCode($secret); echo "Checking Code '$oneCode' and Secret '$secret':n"; $checkResult = $ga->verifyCode($secret, $oneCode, 2); // 2 = 2*30sec clock tolerance if ($checkResult) { echo 'OK'; } else { echo 'FAILED'; }

Running the script provides the following output:

Secret is: OQB6ZZGYHCPSX4AK Google Charts URL for the QR-Code: https://www.google.com/chart?chs=200x200&chld=M|0&cht=qr&chl=otpauth://totp/infoATphpgangsta.de%3Fsecret%3DOQB6ZZGYHCPSX4AK Checking Code '848634' and Secret 'OQB6ZZGYHCPSX4AK': OK
