PHP将soap请求写入文件

Question

what I'm trying to do it setting up an XAMPP apache, creating a script on it, which is once it is called, writing down into a file:

• HTTP header attributes
• content (body - like webservice XML etc.)

This seems to be a small thing, however it looks like I'm not able to find a solution via google... Help would be highly appreciated, thanks in advance!

<?php
$request = "";
//printing headers
foreach (getallheaders() as $name => $value) {
   $request.= "$name: $value\n";
}
//printing body.. this part does not work any of it...
foreach ($_POST as $name => $value) {
   $request.= "$name: $value\n";
}
//$request.="++++++++++++++++++++++\n"
foreach ($_FILES as $name => $value) {
    $request.= "$name: $value\n";
    //$request.="++++++++++++++++++++++\n"
    foreach ($value as $name2 => $value2) {
        $request.= "$name2: $value2\n";
        //$request.="++++++++++++++++++++++\n"
    }
}
$request.=$_FILES['document.xml']['D:\Software\xampp\tmp\phpA521.tmp'];
$request.=@file_get_contents('php://input');
file_put_contents('result/'.date('Y-m-d H_i_s').'.log',$request);
?>

The $_POST variable only gets populated for specific request types. The docs describe $_POST as:

An associative array of variables passed to the current script via the HTTP POST method when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.

In your case the Content-Type is different and should/will be specified as:

Content-Type: application/soap+xml;

There is a similar restriction on the $_FILES variable. The docs state:

Note:
Be sure your file upload form has attribute enctype="multipart/form-data" otherwise the file upload will not work.

The global $_FILES will contain all the uploaded file information.

To get access to the posted data, do as explained in the documentation on I/O streams :

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input

So you would do this as follows:

$postedData = file_get_contents('php://input');

You could then parse this as XML:

$xmlData = simplexml_load_string(trim($postedData));
