Description:
------------
The SoapServer class doesn't seem to support processing SOAP Headers.

An example SOAP request to the server looks as this:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
	<SOAP-ENV:Header>
		<m:RequesterCredentials xmlns:m="http://localhost/3.0.2/soap/">
			<username>String</username>
			<password>String</password>
			<signature>String</signature>
		</m:RequesterCredentials>
	</SOAP-ENV:Header>
	<SOAP-ENV:Body>
		<m:GetAvailableStockQuantityRequest xmlns:m="http://localhost/3.0.2/soap/">
			<itemID>-0</itemID>
		</m:GetAvailableStockQuantityRequest>
	</SOAP-ENV:Body>
</SOAP-ENV:Envelope>


As you can see, the header "RequesterCredentials" is sent to the server. I need to process and validate "RequesterCredentials" on the server side, but the class SoapServer doesn't seem to support of processing headers (i.e. I cannot implement header checks if I wanted to using SoapServer).

If a developer can use SoapServer to process headers, it is a documentation issue. 

If a developer cannot use SoapServer to process headers, it should made clear within the documentation.

Hello Tony,

is there a (pre-)documentation for 5.2 available?
 [2006-08-03 10:18 UTC] tony2001@php.net 
All docs are available @ php.net.
There shouldn't be any differencies in SOAP except for bugfixes.
 [2006-08-03 12:06 UTC] hummel at channeladvisor dot de 
I guess my request was not clear.

A developer can register SOAP functions via calling

$server = new SoapServer("<somewsdl>");
$server->addFunction("<functionname>");

but there seems no method to do

$server->addHeaderFunction("<headerfunctionname>");

Given my example above, I want to process the header "RequesterCredentials", so I would have to do something like

$server->addHeaderFunction("RequesterCredentials");

It is not documented wether header processing is possible using SoapServer or not.

If it's not documented - it is not possible.
Please express your thoughts more clearly next time.
Thank you.

Dear Tony,

after reading my initial request, it is certainly clear what my request was. 

However, it should be documented that processing SoapHeaders within a SoapServer is not possible.
 [2006-08-03 13:00 UTC] tony2001@php.net 
Please explain - what exactly should be documented?
The fact that there is no such function?
 [2006-08-03 13:13 UTC] hummel at channeladvisor dot de 
On the documentation page

http://de2.php.net/manual/en/function.soap-soapserver-addfunction.php

add the following note below the existing note:

Note: You cannot process SOAP headers using addFunction. The only way to process SOAP headers is to extract them via $HTTP_RAW_POST_DATA and process them before calling SoapServer->handle().
 [2007-02-24 21:53 UTC] dmytton@php.net 
Processing headers is nothing to do with addFunction(). This isn't really a documentation issue because there is no function to process headers. I'm going to close this as a documentation issue. If you want to request it as a feature, reopen as a feature request.
 [2010-07-25 00:53 UTC] ruben at messwithyou dot com 
Please reopen this as a feature request, 

Being able to process the send headers would be a lot better for sending meta data 
along which I need!
 [2013-11-18 22:03 UTC] markfb at vorensys dot com 
The fact that you can't process soap headers via addFunction() seems like a glaring omission to me. I've just wasted a lot of time figuring this out and I agree that it should be handled either via a feature request or by clearly stating this limitation in the documentation.
