在 null 上调用成员函数 sendEmail()

Question

我正在使用 AWS 示例来调用适用于 PHP 的 AWS 开发工具包。将代码转换为函数时，出现以下错误：未捕获错误：调用成员函数 sendEmail((

第 41 行似乎是问题所在：$result = $SesClient->sendEmail([

我尝试删除结果变量并注释掉其用法

当我运行代码并且它不是一个功能时，它工作正常，我不确定我在这里做错了什么，我确信这可能是一个简单的错误。

提前感谢您的帮助

Answer 1

尝试在 send_email 函数中声明$SesClient

Answer 2

它在没有函数的情况下工作，正如您在函数外部声明$SesClient一样。在函数之后声明它 - 或通过以下方式将其传递给函数

function function send_email($recipient, $message, $subject, $SesClient) {
/* snip */
}
echo send_email('[e-mail]', 'test', 'test subject', $SesClient);
