How to access POST data in PHP?

Question

Hello,

I need to write PHP page which would accept XML document sent over POST request. Request itself looks like this:

POST /mypage.php HTTP/1.1
Host: myhost.com
Content-Type: application/xml
Content-Length: ...

<?xml version="1.0" encoding="utf-8"?>
<data>
 ...
</data>

This is not data from some HTML form, just plain XML document. I am not sure how to access this XML in my PHP code. Any hints? (Pointer to correct functions in manual is fine)

(I am sorry if this is too trivial... I cannot find correct functions in manual. Normally I don't do PHP)

Answer 1

Try the $HTTP_RAW_POST_DATA variable or the php://input stream.

Answer 2

Read from php://input. For example, you could use:

$rawdata = file_get_contents('php://input');

or

$rootNode = simplexml_load_file('php://input');

The alternative, using $HTTP_RAW_POST_DATA, works, too - but it's slower and needs the PHP configuration always_populate_raw_post_data.

Answer 3

http://us.php.net/manual/en/reserved.variables.httprawpostdata.php

$HTTP_RAW_POST_DATA should be available assuming the content-type of the request was not multipart/form-data

Answer 4

If you use print_r($_POST); you will be able to see what you got. Unless i'm missing something... Edit: nvm, totaly forgot about Raw Data :/

Answer 5

$HTTP_RAW_POST_DATA

or

php://input

Answer 6

You probably want to use the PHP input. Something like

$postText = trim(file_get_contents('php://input'));
