You can't.

你不能。

1. PHP runs on the server and outputs some text.
2. The text is sent to the browser
3. The browser interprets the text as HTML / JavaScript / etc

1. PHP 在服务器上运行并输出一些文本。
2. 文本发送到浏览器
3. 浏览器将文本解释为 HTML / JavaScript / 等

The PHP has finished running by the time the JavaScript is executed.

到执行 JavaScript 时，PHP 已完成运行。

If you want to pass data back you need to make a newHTTP request and run a PHP script from scratch.

如果您想将数据传回，您需要发出一个新的HTTP 请求并从头开​​始运行 PHP 脚本。
