PHP 8.2 issue with `${var}` declarations

[scottchiefbaker]

FYI:

PHP Deprecated:  Using ${var} in strings is deprecated, use {$var} instead in /var/www/html/scott/rats/GoogleAuthenticator/PHPGangsta/GoogleAuthenticator.php on line 112

Super easy fix.

English (machine translation)：
I'm also experiencing this issue, but judging by the activity, it shouldn't be maintained anymore, so I'll have to deal with it on my own.
The way I handled it is as follows, hopefully it can be a reference for people encountering the same problem:

Comment out line 112 and replace it with the following:

        return sprintf('https://api.qrserver.com/v1/create-qr-code/?data=%s&size=%dx%d&ecc=%s',
            $urlencoded, $width, $height, $level);

If you don't use this method getQRCodeGoogleUrl(), you can also just delete the part I selected.

中文回复：
我也遇到了这个问题，不过从活跃度上看，应该不在维护了，只能自行处理了。
我的处理方法如下，希望可以给遇到相同问题的人们一个参考：

将 112 行注释，并替为如下写法：

        return sprintf('https://api.qrserver.com/v1/create-qr-code/?data=%s&size=%dx%d&ecc=%s',
            $urlencoded, $width, $height, $level);

如果并没有使用此方法 getQRCodeGoogleUrl() ，也可以直接删除我选中的部分
