PHP - How to set footer in SoapClient - php

Question

With PHP, I need to send a SOAP request with a parameter (Hash) in the footer. I'm using SoapClient but I can not figure out how to do this, neither in internet searches, nor in documentation.
This is the envelope I used in the SoapUI tool to test:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:abc="" xmlns:abc1="" xmlns:abc2="">
<soapenv:Header/>
<soapenv:Body>
<abc:Method>
<!--Optional:-->
<abc:request>
<abc1:Header>
<abc1:Username>Username</abc1:Username>
<abc1:Password>Password</abc1:Password>
<!--Optional:-->
<abc1:PublicKeyUid></abc1:PublicKeyUid>
</abc1:Header>
<abc1:Body>
<abc2:Id></abc2:Id>
</abc1:Body>
<abc1:Footer>
<abc1:Hash></abc1:Hash>
</abc1:Footer>
</abc:request>
</abc:Method>
</soapenv:Body>
</soapenv:Envelope>
There is The SoapHeader class e the SoapClient::__setSoapHeaders method but I find nothing related to the footer.
I do not have access to the server and should follow this structure mentioned above.
What I need to know is how to send the HASH parameter that is inside the footer with SoapClient.
Thanks in advance for any help or suggestion.

As IMSoP and axiac have commented, the footer (<abc1: Footer>) is just a sub-structure of the envelop body and not a standard XML envelop element. I had not realized this and so I did not find it in the documentation.
So to send HASH to the requested structure, I need to pass a multidimensional array on the body element. The code looks like this:
$arrParameters = [
'request'=>[
'Header'=>[
'Username'=>$strUsername,
'Password'=>$strPassword
],
'Body'=>[
...
],
'Footer'=>[
'Hash'=>$strHash
]
]
];
$SoapClient = new SoapClient(<WSDL URL>);
$resp = $SoapClient->method($arrParameters);
Thank you IMSoP and axiac!
