将XML帖子从“ php：// input”转储到文件 [英] Dump XML Posts from 'php://input' to file

问题描述

我正在尝试为xml回发侦听器编写解析器，但似乎无法将其转储为示例的xml。 API支持人员告诉我使用 DOMDocument，也许是 SimpleXML？无论如何，这里是代码：（谢谢！）

I'm trying to write a parser for a xml postback listener, but can't seem to get it to dump the xml for a sample. The API support guy told me to use 'DOMDocument', maybe 'SimpleXML'? Anyways here's the code: (thanks!)

<?php
$xml_document = file_get_contents('php://input');
$doc = new DOMDocument();
$doc->loadXML($xml_document);
$doc->save("test2/".time().".sample.xml").".xml");
?>

推荐答案

如何使用它来创建XML文件？ / p>

How about use this to create an XML file?

/**
 * Will output in a similar form to print_r, but the nodes are xml so can be collapsed in browsers
 *
 * @param mixed $mixed
 */
function print_r_xml($mixed)
{
    // capture the output of print_r
    $out = print_r($mixed, true);

    // Replace the root item with a struct
    // MATCH : '<start>element<newline> ('
    $root_pattern = '/[ \t]*([a-z0-9 \t_]+)\n[ \t]*\(/i';
    $root_replace_pattern = '<struct name="root" type="\\1">';
    $out = preg_replace($root_pattern, $root_replace_pattern, $out, 1);

    // Replace array and object items structs
    // MATCH : '[element] => <newline> ('
    $struct_pattern = '/[ \t]*\[([^\]]+)\][ \t]*\=\>[ \t]*([a-z0-9 \t_]+)\n[ \t]*\(/miU';
    $struct_replace_pattern = '<struct name="\\1" type="\\2">';
    $out = preg_replace($struct_pattern, $struct_replace_pattern, $out);
    // replace ')' on its own on a new line (surrounded by whitespace is ok) with '</var>
    $out = preg_replace('/^\s*\)\s*$/m', '</struct>', $out);

    // Replace simple key=>values with vars
    // MATCH : '[element] => value<newline>'
    $var_pattern = '/[ \t]*\[([^\]]+)\][ \t]*\=\>[ \t]*([a-z0-9 \t_\S]+)/i';
    $var_replace_pattern = '<var name="\\1">\\2</var>';
    $out = preg_replace($var_pattern, $var_replace_pattern, $out);

    $out =  trim($out);
    $out='<?xml version="1.0"?><data>'.$out.'</data>';

    return $out;
}

在我的应用程序中，我将所有$ _POST变量都发布到了它：

Im my application I posted all of the $_POST variables to it:

$handle = fopen("data.xml", "w+");
$content = print_r_xml($_POST);
fwrite($handle,$content);
fclose();
