Get size of POST-request in PHP

Question

Is there any way to get size of POST-request body in PHP?

Answer 1

If you're trying to figure out whether or not a file upload failed, you should be using the PHP file error handling as shown at the link below. This is the most reliable way to detect file upload errors:

If you need the size of a POST request without any file uploads, you should be able to do so with something like this:

$request = http_build_query($_POST);
$size = strlen($request);
