php Get data from url
提问by user1411837
I have a system where in users can create forms dynamically. Once the form is created a unique URL is generated and stored in the database . These URL's are for calling the form back when the users type it out in the browser .
我有一个系统，用户可以在其中动态创建表单。一旦创建了表单，就会生成一个唯一的 URL 并将其存储在数据库中。这些 URL 用于在用户在浏览器中输入表单时回调表单。
Now i want a particular file to read the url when the users type out the generated url in the browser , so that i can get the last segment of the url which is unique and fetch the respective data at run time .
现在我想要一个特定的文件在用户在浏览器中输入生成的 url 时读取 url，这样我就可以获得 url 的最后一段，这是唯一的，并在运行时获取相应的数据。
I cant seem to figure out how to do that .
我似乎无法弄清楚如何做到这一点。

If you are trying to receive data from a URL string, you will need to use the $_GETvariable .
如果您尝试从 URL 字符串接收数据，则需要使用$_GET变量 。
If the url is http://domain.com/page.php?var1=some-string
如果网址是 http://domain.com/page.php?var1=some-string
You would retrieve var1like so:
你会var1像这样检索：
<?php
$var1 = $_GET['var1'];
echo $var1; //would output "some-string"
?>
Is this what you're asking or is it something more in-depth?
这是您要问的问题还是更深入的问题？
