我正在将数据发送到php页面，以便通过jQuery和ajax进行处理，结果我会得到

success: function(data){
mydata = data;
}

my data is an url that looks like mydata = https://myurl.com. Now I want to set mydata to a php variable and use it again inside another function in the main page, means: to set $url = mydata;. How can I do that?

我的数据是一个看起来像mydata = https://myurl.com的网址。现在我想将mydata设置为php变量并在主页面中的另一个函数内再次使用它，意思是：设置$ url = mydata;。我怎样才能做到这一点？

PHP scripts execute when you open a file and before everything else. Ajax calls exectue when the Javascript is completely loaded. (After php).

PHP脚本在您打开文件时以及其他所有文件之前执行。当Javascript完全加载时，Ajax调用exectue。（在PHP之后）。

So you cant do it. could you give me more detail about what do you want to do?

所以你不能这样做。你能告诉我你想做什么的更多细节吗？

You can do that using Post via a from, GET via a query string or you can use cookie like in this solution

您可以使用Post通过from，GET通过查询字符串来执行此操作，或者您可以使用此解决方案中的cookie

You can send the mydata variable to PHP by calling an XMLHttpRequest() via AJAX.
For example

您可以通过AJAX调用XMLHttpRequest（）将mydata变量发送到PHP。例如

var ajax = new XMLHttpRequest(); // Create new request
ajax.open("POST", "mainpage.php"); // Open the file where you want to send it with POST
ajax.send("mydata="+mydata); // Send mydata variable to PHP

Then in PHP you can check for the variable mydata

然后在PHP中，您可以检查变量mydata

if(isset($_POST['mydata'])){
    // do something
}
