i have found alternative way solve problem

i prepared , envelope xml , send request using curl has envelope parameter.you can refer following code;

$username = ""; $password = ""; $webserviceurl = "";  $xml = '<?xml version="1.0" encoding="utf-8"?> <soap:envelope xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">   <soap:body>     <remotemethod xmlns="http://your.service.url/">       <parameter_1>your_paramter_1</parameter_1>       <parameter_2>your_paramter_2</parameter_2>       ........       <parameter_n>your_parameter_n</parameter_n>     </remotemethod>   </soap:body> </soap:envelope>';   $ch = fopen("envelope.xml", "w"); fwrite($ch, $xml);  $cmd = 'curl -d @envelope.xml -h "content-type: text/xml;charset=utf-8 " --user ' . $username . ':'.$password.' --ntlm ' . $webserviceurl . ' > requestresult.xml'; shell_exec($cmd); fclose($ch);
