How can I make a soapmsg in client like this:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<MMS:AuthPassword>111111</MMS:AuthPassword>
</MMS:Auth>
</soapenv:Header>
<soapenv:Body>
<MMS:Title xmlns:MMS="http://www.xieheng.com/xiehengmms">happy new year</MMS:Title>
<MMS:Phone xmlns:MMS="http://www.xieheng.com/xiehengmms">135654418888</MMS:Phone>

Check out nusoap samples first.
You don't need to write xml when you develop with nusoap.
XML will be written for you by it.

I would also suggest to use NuSoap Client of PhpED - it generates the whole code for you, I didn't have to do anythingj just pointed yo wsdl - and that was pretty much it. I am not a big SOAP pro honestly
