The error is in the paypal\rest-api-sdk-phppackage you are using. The version of the package you are using is, apparently, not exactly compatible with PHP 7.2.
错误出在paypal\rest-api-sdk-php您正在使用的包中。您使用的软件包版本显然与 PHP 7.2 不完全兼容。
The specific error you are getting has been fixed in the latest version of the package (1.13.0). Update the package to the latest version, and this issue will be fixed. I cannot say what other issues may pop up, though.
您遇到的特定错误已在最新版本的软件包 ( 1.13.0) 中得到修复。将软件包更新到最新版本，此问题将得到修复。不过，我不能说可能会出现什么其他问题。
In the 1.12.0version, the specific line that is failing is:
在1.12.0版本中，失败的特定行是：
} elseif (sizeof($v) <= 0 && is_array($v)) {
In PHP 7.2, if $vis not Countable, the sizeof()call will emit a warning, and Laravel will turn that warning into an exception.
在 PHP 7.2 中，如果$v不是 Countable，则sizeof()调用会发出警告，Laravel 会将警告转换为异常。
In the 1.13.0version, they updated the condition to be
在1.13.0版本中，他们将条件更新为
} elseif (is_array($v) && sizeof($v) <= 0) {
Now, sizeof()will only be called when $vis an array, and therefore is guaranteed to be Countable, thus eliminating the warning.
现在，sizeof()只会在$v是数组时调用，因此保证是可数的，从而消除警告。
