在PHP中解析传入的请求

Question

If the incoming PHP possible requests can be the following

1)http://wwww.test.com/api.php?device_id=xxxx&user_name=xxxx&pass_word=xxxx&num_request=xxxx&num_site=xxxx;

how do I extract the user_name field from the above in my api.php code?

Answer 1

Those values are passed via a standard GET request accessible like this:

$deviceid = $_GET['device_id'];

Be aware that this value is unsanitized and open to modification from the user which could ultimately end up with SQL injection depending on your usage of the value.
