PHP: Possible to automatically get all POSTed data?

Question

Simple question: Is it possible to get all the data POSTed to a page, even if you don't know all the fields?

For example, I want to write a simple script that collects any POSTed data and emails it. I can foresee that the fields in the form are likely to change a lot over time, and so to save myself some time in the long run, I was wondering if I could write something that automatically gathered everything?

Is it possible?

Answer 1

Sure. Just walk through the $_POST array:

foreach ($_POST as $key => $value) {     echo "Field ".htmlspecialchars($key)." is ".htmlspecialchars($value)."<br>"; } 

Answer 2

No one mentioned Raw Post Data, but it's good to know, if posted data has no key, but only value, use Raw Post Data:

$postdata = file_get_contents("php://input"); 

PHP Man:

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".
