LiveDocx and nuSoap.... Easiest way..?

Hi there ppl...
I need to use a php function to fill a .docx template with some info of my Database. I was using some phpclass with rich text, but is really hard to get something nice... So i was doing some research and found this LiveDocx that come with Zend FW. But, i'm not using Zend, so i went a lil deeper and found a way to use LD without Zend...
I downloaded the libs, put them in my folder and tried to do one of the examples of the tutorial. The code is this one:


if (isset($_POST['exportar'])){

        #!/usr/bin/php

 

        // Turn up error reporting

        error_reporting (E_ALL ^ E_DEPRECATED);

         

        // Turn off WSDL caching

        ini_set ('soap.wsdl_cache_enabled', 0);

         

        // Define credentials for LD

        define ('USERNAME', 'xxxxxx ');

        define ('PASSWORD', 'xxxxxx');

         

        // SOAP WSDL endpoint

        define ('ENDPOINT', 'https://api.livedocx.com/1.2/mailmerge.asmx?WSDL');

         

        // Set include path

        set_include_path (dirname(__FILE__) . '/functions/lib');

         

        // Include NuSOAP libary

        require_once 'nusoap.php';

        

        

        // Instantiate SOAP object and log into LiveDocx

 

        $nuSoap = new nusoap_client(ENDPOINT, true);

         

        // Set charset encoding for outgoing messages

         

        $nuSoap->soap_defencoding = 'UTF-8';

         

        // Log into SOAP service

         

        $nuSoap->call('LogIn',

            array(

                'username' => USERNAME,

                'password' => PASSWORD

            )

        );

         

        // Upload template

         

        $data = file_get_contents('./license-agreement-template.docx');

         

        $nuSoap->call('SetLocalTemplate',

            array(

                'template' => base64_encode($data),

                'format'   => 'docx'

            )

        );

         

        // Assign data to template

         

        $fieldValues = array (

            'software' => 'PetroAlianza Worksite',

            'licensee' => 'Gerardo Leal',

            'company'  => 'PetroAlianza',

            'date'     => date('F d, Y'),

            'time'     => date('H:i:s'),

            'city'     => 'Ciudad Ojeda',

            'country'  => 'Venezuela'

        );

         

        $result = $nuSoap->call('SetFieldValues',

            array(

                'fieldValues' => nuSoap_assocArrayToArrayOfArrayOfString($fieldValues)

            )

        );

         

        // Build the document

         

        $nuSoap->call('CreateDocument');

         

        // Get document as PDF

         

        $result = $nuSoap->call('RetrieveDocument',

            array(

                'format' => 'docx'

            )

        );

         

        $data = $result['RetrieveDocumentResult'];

        file_put_contents('./license-agreement-document.docx', base64_decode($data));

        

        // Log out (closes connection to backend server)

 

        $nuSoap->call('LogOut');

 

        unset($nuSoap);

 

        print('DONE.' . PHP_EOL);

    }

But when i try to export it i got this line:

[B]Fatal error:[/B] Call to undefined function nuSoap_assocArrayToArrayOfArrayOfString() in C:\xampp\htdocs\workbench\doc gen\doc_gen.php on line 75

So, What is going on..?.. Need some help there...

PD: If there is a better way to get this done. please let me know... :)
