php - how to get an email address passed in url

Question

I have an email address passed as a variable in the url as part of the link. I need to be able to retrieve this email address and then insert it into a database. the issue is i cannot seem to be able to retrieve the email address from the url. This is the code Im using to get it:

if(isset($GET['email'])){
 $email = $_GET['email'];
 }

The url looks something like this www.sumwebsite.com?email=aemail@email.com Any ideas? As far as I have been able to see my code is right, so I am at a complete loss as to why it is not working.

Answer 1

if(isset($GET['email'])){
          ^-- missing a _

应该

if(isset($_GET['email'])){
          ^---note the _

Answer 2

当您使用电子邮件创建链接时，您应该对其进行urlencode()。当您使用$_GET从 PHP 获取它时，您应该使用urldecode()它。

正如评论中所说，$_GET 已经透明地运行 urldecode()，所以不需要它。确实需要 urlencode()。此外，作者犯了使用 $GET 而不是 $_GET 的错误。
