SAPNWRFC Connection how to WRITE DATA php

问题

Below code used to fetch and display data from PHP

<?php
use SAPNWRFC\Connection as SapConnection;
use SAPNWRFC\Exception as SapException;
//print_r($_POST);
$config = [
    'ashost' => '###.###.###.###',
    'sysnr'  => '##',
    'client' => '###',
    'user'   => '####',
    'passwd' => '*******',
    'trace'  => SapConnection::TRACE_LEVEL_OFF
];
$sap = false;
$sapMTList = "";
try {
    $sap = new SapConnection($config);
    $result=$sap->getFunction("ZBAPI_SAMPLE_LIST_V1");
    $parms = [
       // 'I_MATTYPE' => 'FERT', 'I_PLANT' => 'XXXX'
        "I_MATTYPE" => "FERT", "I_PLANT" => "XXXX"
        ];
    if(isset($_POST['submit']) && $_POST['submit'] === 'sap_params'){
        $plantNumber="";
        if(isset($_POST['plantNumber'])){
            $plantNumber=$_POST['plantNumber'];
        }
        $parms = [
            "I_MATTYPE" => "FERT", "I_PLANT" => "$plantNumber"
        ];
    }
    $test = $result->invoke( $parms);
    $sapMTList = array_shift($test);
} catch(SapException $ex) {
    echo 'Exception: ' . $ex->getMessage() . PHP_EOL;
}

?>
<?php
 if($sapMTList != "" && !empty($sapMTList)){
        $i=0;
        foreach ($sapMTList as $column){
          // displays data
       }
?>

The code works fantastic to read data. ref: https://gkralik.github.io/php7-sapnwrfc/introduction.html

Can anyone tell me how to write data?

Tried my level best to find resource but couldn't find anywhere. Any help would be highly appreciated. Thanks in advance.

PHP Version 7.0.21

SAPNWRFC VERSION Version 1.1.2

SAP NW RFC SDK 7200.0.33

iis server (in 2k12)
