[PHP] reading incoming xml
I am running apache with php. I set up a curl script to send an xml request to the php page I'm authoring and want to handle the xml on the incoming message. My $_POST array is empty though. Is there some other place I should be looking? $_SERVER shows the incoming message as a post but again the data isn't there. Does apache/php place the xml in some other location for me to access?

did you use a request header to somehow set a mime type to indicate youre
looking for xml? could you show us this request, im not sure how to request
for xml specifically..
My $_POST array is empty though.
is this on the system where the xml will be sent from? you have to
populate the post fields in the request by using the curl option
CURLOPT_POST to indicate you are posting, and CURLOPT_POSTFIELDS, to pass an
array of parameters that will be used as post fields. then the $_POST array
will be populated on the provider system.
Is there some other

still curious if youre looking on the consumer (system sending curl request)
or the provider, (system providing the xml data via response).

depending on how you configure curl, the data can be in different places.
the easiest way (i think) is to use the CURLOPT_RETURNTRANSFER option. then
the response will be returned from curl_exec() (rather than a boolean
success flag).
here is sample code from a consumer and a provider; theyre up on my server
so you can try using the consumer if you want.

Re: [PHP] reading incoming xml
I'm sending from a php cli with:
$post = '?xml version=1.0
encoding=UTF-8?Data'.$vendorCompanyID.'/Data';
$message = generatePage($page, $post);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://myserver/mytestpage.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $message);
$data=curl_exec($ch);
I've the server page (mytestpage.php) set up as:
echo hello\n;
print_r($_SERVER);
where I replace SERVER with POST etc and I can't find the string '?xml
version=1.0 encoding=UTF-8?Data'.$vendorCompanyID.'/Data' in
the $data output. I do get the hello so I know I am hitting the server
and when it is set to $_SERVER as listed above I get the expected array
but $_POST is empty.

hmm, it looks to me like you want to post a bunch of raw data to the
server. im not sure exactly how to do that w/ the php curl functions...
everything ive seen uses CURLOPT_POSTFIELDS to supply an associative array
of data to be posted. in this case you could easily send you data across by
choosing a name for the index, something like 'postdata', anything will do,
then it will be accessible on the system youre posting to via
$_POST['postdata'].
also, inlooking at your usage of CURLOPT_CUSTOMREQUEST, i dont believe youre
using it correctly, i think youre just supposed to put a string
representing the desired http method in there, so something like 'HEAD',
'PUT', or in this case 'POST'. then you would supply the data as i said
earlier, using CURLOPT_POSTFIELDS. so in all, i think something like this
would work for you,
$post = '?xml version=1.0
encoding=UTF-8?Data'.
$vendorCompanyID.'/Data';
$message = generatePage($page, $post);
$ch = curl_init();
curl_setopt($ch,
CURLOPT_URL,'https://myserver/mytestpage.php'https://myserver/mytestpage.php%27
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, array('postdata' = $message));
$data=curl_exec($ch);
and also, in reading the warning about CURLOPT_CUSTOMREQUEST, you might just
go with CURLOPT_POST = true, since you arent using an obscure http method.
im not sure exactly how to determine if the server supports this method or
not. anyway, i found this in 'man curl_easy_setopt' (thats the manpage for
the c function php uses for the CURLOPT_CUSTOMREQUEST option).
Many people have wrongly used this option to replace the
entire request with their own, including multiple headers and POST contents.
While that might
work in many cases, it will cause libcurl to send invalid
requests and it could possibly confuse the remote server badly. Use
CURLOPT_POST and CUR-
LOPT_POSTFIELDS to set POST data. Use CURLOPT_HTTPHEADER to
replace or extend the set of headers sent by libcurl. Use
CURLOPT_HTTP_VERSION to change
HTTP version.

Re: [PHP] reading incoming xml
Thanks for the help Nathan. What I'm looking for though is how to accept and read the incoming XML the way I was sending it in curl. I am currently using that curl mechanism on the cli to connect to another remote XML server successfully. I want to keep that side of the equation the same. I need to find out if I can access the incoming data on the server side. I don't need or want to use curl on the server side. I just want to handle the incoming XML. How does SOAP and XML-RPC get to the incoming XML? Is the incoming SOAP and XML-RPC packages arriving in html posts? I tried looking at the nusoap code to determine this to no avail.

Larry,
I'm sorry that I'm not certain what you mean by remote XML
server, since XML is a markup language and a server (in this context)
insinuates an HTTP (protocol) web server, but perhaps a combination of
file_get_contents() and the information from the following manual
entry will help you.

RE: [PHP] reading incoming xml
You can get what you post either with:
$postText = trim(file_get_contents('php://input');
Or with:
$postText = $GLOBALS[HTTP_RAW_POST_DATA];
About HTTP_RAW_POST_DATA http://us2.php.net/manual/en/reserved.variables.php
Read the notes here http://us2.php.net/variables.predefined
It should be noted that $HTTP_RAW_POST_DATA only exists if the encoding type of
the data is -not- the default of application/x-www.form-urlencoded, and so, to
accessing raw post data from an HTTP form requires setting enctype= in your
HTML.
So, if $RAW_POST_DATA doesn't exist, it is because you should be able to use
$_POST (unless you set PHP to always populate raw post data in php.ini). The
preferred method is, however, to read 'php://input'
Then after you get the XML body, you must use one of the XML extensions
available in PHP to parse the XML data (search for it as it's not part of this
help pack ;) ).

RE: [PHP] reading incoming xml
This is what I was looking for. Thank you. I could not change the
client since that client is being used for other servers in its current
configuration. All I needed was a way to get to the XML string coming
in.
$postText = trim(file_get_contents('php://input');
worked perfectly. Now that I have this blob of XML I can give it to
simpleXML or another parser I was recently shown to work with it. I'm
surprised it was so difficult to find. $GLOBALS['HTTP_RAW_POST_DATA']
was empty by the way and that I'd seen before.
Also, sorry if I threw anyone off by referring to the other server the
client works with as an XML server. I only referred to it as such
because it is a server that accepts XML input and responds with XML
output to a number of clients. It is not used as a typical html server
for browsing etc.
Anyway, I was looking to get a hold of the raw data coming in and it
looks like this was it. I really do appreciate the help...
