Accept: text/xml, text/html, text/plain, */*
Host: myhost.com
Content-Length: 752
Cache-Control: no-cache

How can I capture the BASE64 data and write it to a file, I tried to dump the $_POST variables but I get nothing, tried with $_REQUEST or serialize($_REQUEST) and all I get is:

Array
(
)

How can I capture an undefined post data? Thanks!

PHP only decodes URL encoded POST data into $_POST. For data of any other format, see ^ — deceze

It can be found in $HTTP_RAW_POST_DATA:

echo $HTTP_RAW_POST_DATA;

Or:

echo file_get_contents("php://input");

Manual.

You can then write it to a file with file_put_contents() or any of the other methods to write to a file.
