Not the way your code sample is structured, no. PHP is a server-side language and Javascript is a client-side language. PHP is out of scope by the time any client-side script executes.
不是您的代码示例的结构方式，不是。PHP 是一种服务器端语言，而 Javascript 是一种客户端语言。当任何客户端脚本执行时，PHP 已超出范围。
If you need to pass an object from the browser to your server you can use XMLHttpRequest (commonly referred to as AJAX).
如果您需要将对象从浏览器传递到您的服务器，您可以使用 XMLHttpRequest（通常称为 AJAX）。

To send a Javascript variable back to PHP, you need to do an AJAX request:
要将 Javascript 变量发送回 PHP，您需要执行 AJAX 请求：
<script language="javascript" >
xmlhttp.open("GET","getvalue.php?id="+id,true);
xmlhttp.send();
</script>
And in getvalue.php you'd have:
在 getvalue.php 中，您将拥有：
<?php
$getthevalueofid = $_GET['id'];
?>

No way to do this. Use Ajax to pass javascript variable to php
没有办法做到这一点。使用 Ajax 将 javascript 变量传递给 php
