Execute SOAP using cURL - php

Question

I am trying to execute an SOAP-function using cURL (because I get an error using the SoapClient().
This is my code (that is halfway working)
$credentials = "username:pass";
$url = "https://url/folder/sample.wsdl";
$page = "/folder";
$headers = array(
"POST ".$page." HTTP/1.0",
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
"Cache-Control: no-cache",
"Pragma: no-cache",
"SOAPAction: \"customerSearch\"",
"Authorization: Basic " . base64_encode($credentials)
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_USERAGENT, $defined_vars['HTTP_USER_AGENT']);
$data = curl_exec($ch);
The problem is that the SOAP-action is not being performed. And I also need to pass arguments to the action. Is this even possible?

You need to specify the cURL options to POST, and set the body of the request - if your not sending a body, there's no point in a POST request (and more importantly, it isn't SOAP). Building a complete HTTP request header just won't cut it.
$credentials = "username:pass";
$url = "https://url/folder/sample.wsdl";
$body = ''; /// Your SOAP XML needs to be in this variable
$headers = array(
'Content-Type: text/xml; charset="utf-8"',
'Content-Length: '.strlen($body),
'Accept: text/xml',
'Cache-Control: no-cache',
'Pragma: no-cache',
'SOAPAction: "customerSearch"'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_USERAGENT, $defined_vars['HTTP_USER_AGENT']);
// Stuff I have added
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, $credentials);
$data = curl_exec($ch);
