mysql - php script to log the raw data of POST

Question

I am sending data using HTTP POST to my server. But in the server, I am not receiving the data. And somehow I don't have any way to check the data (or debug script) on client side. But on client side I am getting HTTP 200, means data is sent. Also I can see the connection and data sending was successful. However log in the server doesn't contain the data (only the number of bytes).

How can I log the raw POST data that was sent to the server?

FYI, here client is an embedded device with very limited capability. SO, is this problem. So, I can not check "print_r" or "echo"

You can see the content of post data inline (not for production) with:

print_r($_POST);

Or if you want to see POST, GET and COOKIE data:

print_r($_REQUEST);

If you need to log, since the client is very limited - try outputting the POST data to a file:

file_put_contents("post.log", print_r($_POST, true));
