如何获取包含点的网址[关闭]

Question

I'm trying to get the url from sample below link using php get but I'm missing something.

Example link:

example.com/go/?url=http://example2.com

and using the below code:

<?php
$url = $_GET["url"];
echo $url;
?>

and all i can see is 403 error, I see now that error is from dot (.) in url, but how can I correct it?

Answer 1

You should urlencode the parameter to ensure its not being interpreted wrong, when sending the request to the server and use urldecode on the server to revert it back.

Also the 403 error code is the web serving telling you permission denied for some reason you have to investigate. Maybe look at the logs for your webserver.
