我有一个证书（.cer文件）及其公钥。我需要使用这个密钥和肥皂消息体创建一个签名，还需要在soap消息的标题部分添加这个生成的签名。像
<?php
if($errorMsg == ''){
//Make the message.
$message ="
First Name: ".$fname.".\n
Last Name: ".$lname."\n
Website: ".$website."\n
Did They Like the Site? ".$likedsite."\n
How They Found Us. ".$findoption."\n
Question/Comments:\n
".$comments." ";
$message = wordwrap($message, 70);
$headers = "From: $email";
mail("me@gmail.com", $subject, $message, $headers);
}else{
// Show $errorMsg
}
?>
基本上我需要在标题部分中添加<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
