PHP is executed before javascript. You can't do that. PHP is server based, JavaScript is client based.
PHP 在 javascript 之前执行。你不能那样做。PHP 是基于服务器的，JavaScript 是基于客户端的。
When PHP is finished executing, it outputs HTML. In the HTML there can be JavaScript code also. So PHP can 'control' JavaScript by outputting JavaScript code to the page, but not the other way around. You'd have to use Ajax-call for that.
当 PHP 完成执行时，它会输出 HTML。在 HTML 中也可以有 JavaScript 代码。因此 PHP 可以通过将 JavaScript 代码输出到页面来“控制” JavaScript，但反过来不行。为此，您必须使用 Ajax 调用。

Javascript works on the user's computer, PHP works on your server. In order to send variables from JS to PHP and vice versa, you need communication such as a page load.
Javascript 在用户的计算机上运行，PHP 在您的服务器上运行。为了将变量从 JS 发送到 PHP，反之亦然，您需要进行诸如页面加载之类的通信。

Javascript, is a client side script, Where as PHPis a server side script.
Javascript，是客户端脚本，而PHP服务器端脚本也是如此。
The only way you can send data to PHP is through redirectionor ajax.
向 PHP 发送数据的唯一方法是通过redirection或ajax。

You cannot do that this way. You have to transmit values via$_GET, $_POSTor $_COOKIE, afterthe script has been executed by client.
你不能这样做。你要发送的值通过$_GET，$_POST或者$_COOKIE，之后的剧本已经由客户端执行。
