JAX-WS Part 2: PHP-CURL sample client

I'll keep the PHP code minimalistic and will not be creating a SOAP client with PHP. Instead I'll just post a ready-made SOAP xml using CURL and my client certificat/key pair. So the PHP code looks like this:

<?php

// connect to server with client cert and private key
if ($ch = curl_init()){ 

 curl_setopt($ch, CURLOPT_URL,  "https://localhost:8181/ExampleWS/Example");
 curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 1);
 curl_setopt($ch, 'CURLOPT_SSLCERTTYPE',  'PEM');
 curl_setopt($ch, CURLOPT_SSLKEYTYPE, 'PEM');
 curl_setopt($ch, CURLOPT_SSLCERT, 'democompany1.crt');
 curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'changeit');
 curl_setopt($ch, CURLOPT_SSLKEY, 'democompany1.key');
 curl_setopt($ch, CURLOPT_SSLKEYPASSWD, 'changeit');
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
 curl_setopt($ch, CURLOPT_CAINFO, NULL);
 curl_setopt($ch, CURLOPT_CAPATH, NULL);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml', 'SOAPAction: ""') );
 curl_setopt($ch, CURLOPT_POST, 1);
$soap_message = <<<SOAP
<?xml version="1.0" encoding="utf-8" ?>
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 <env:Body>
   <ns2:sampleEcho xmlns:ns2=""><sampleParamStr>Hello World!</sampleParamStr></ns2: sampleEcho >
 </env:Body>
</env:Envelope>
SOAP;
 curl_setopt($ch, CURLOPT_POSTFIELDS, $soap_message);
 echo "Connecting\n";
 $data = curl_exec($ch);
 if ($data) {
  echo  "DATA: ".$data;
 } else {
  echo curl_error($ch);
 }
 echo "\nDone\n";

}


?>

You can run this with PHP-CLI
