在 null 上调用成员函数 sendEmail()

Question

我正在使用 AWS 示例为 PHP 调用 AWS SDK。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([

我试过删除结果变量并注释掉它的用法

当我运行代码和它不是函数时它工作正常，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，因为您在函数外声明了 $SesClient。在函数之后声明它 - 或者通过

将它传递给函数

function function send_email($recipient, $message, $subject, $SesClient) {
/* snip */
}

echo send_email('test@gmail.com', 'test', 'test subject', $SesClient);

在 null 上调用成员函数 sendEmail()

Call to a member function sendEmail() on null

php

amazon-web-services

amazon-ses
