如果您正在谈论发出请求并指定标头，则一种方法是使用CURL：

$data = "<soap:Envelope>[...]</soap:Envelope>"; 
$tuCurl = curl_init();
curl_setopt($tuCurl, CURLOPT_HEADER, 0);
curl_setopt($tuCurl, CURLOPT_URL, "http://example.com/path/for/soap/url/");
curl_setopt($tuCurl, CURLOPT_POST, 1); // if post request
curl_setopt($tuCurl, CURLOPT_POSTFIELDS, $data);
curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($tuCurl, CURLOPT_HTTPHEADER, array("Content-Type: text/xml","SOAPAction: \"/soap/action/query\"", "Content-length: ".strlen($data)));
$tuData = curl_exec($tuCurl); 
if(!curl_errno($tuCurl)){ 
  $info = curl_getinfo($tuCurl); 
  echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url']; 
} else { 
  echo 'Curl error: ' . curl_error($tuCurl); 
} 
curl_close($tuCurl); 
echo $tuData;
