有没有办法在 PHP 中将 XML 文件转换为 JSON [重复]

Question

我正在尝试将我的 xml getDetailsXML.php 文件转换为 JSON。我调用了我的 service.php 页面，该页面处理我对 getDetailsXML.php 的 ajax 请求。在 service.php 中，我正在进行从 XML 到 JSON 的转换，然后发回要显示的数据。

我的服务.php

<?php
     $.ajax({
            url: "getDetailsXML.php?ImageID=" + escape($itemName),
            cache: false,
            dataType: "xml",
            success: function(xml){
                echo json_encode(xml);
        });
echo $itemName[$_REQUEST['ItemName']];;
?>

我的电话是从服务页面获取详细信息。

    function getDetails(itemName) {
        $.getJSON("service.php?ItemName=" + itemName, function(json){
            var descriptionDetails = "<p class='description'>Description: " + this.description + "</p>" + "<p>Price: " + this.price + "</p>";
            $("#detailsPane").append(descriptionDetails);
            var priceDetails = "<p>Price: " + this.price + "</p>";
            $.each(json.resources, function () {
                var url = "<li>" + this.url + "</li>";
                $("#detailsPane").append(url);
            });
        });
    }

我的 getDetailsXML.php 文件

<?php

$details = array (
        'itemGuitar'    =>      
"<?xml version=\"1.0\"?>
<item id=\"itemGuitar\">

header("Content-Type: text/xml");
echo $details[$_REQUEST['ImageID']];

?>

您可以使用simplexml_load_string 将xml 加载到对象。然后使用json_encode获取json字符串。

$result = array_map(function($v){return simplexml_load_string($v, 'SimpleXMLElement', LIBXML_NOCDATA);},$details);
echo json_encode($result);
