我一直在使用simpleXML，我有一个XML文件和一个Son文件，我想在其中保存数据。 如果我这样做：
$TBTweakedAddInfo[] = array(
'test' => $xmlAddPlist->dict->array->dict->array->dict[0]->string[1],
);
然后将数组转换为 json，我得到这个：
{
"test": {
"0": "value from the XML"
}
},
我怎样才能做到这一点
{
"test":"value from plist",
}
这让我一直困扰着我，因为如果我要提取数据来假设一个页面，我将不得不这样做
echo $json->test->{'0'}
这太可怕了
这是 XML 文件。我正确地抓住了这个值，但使用了那个烦人的"0"对象。

当您不确定正在使用的数据结构时，只需从print_r()开始并查看它告诉您的内容。

$pxml = new SimpleXMLElement($xml);
print_r($pxml);
结果：
SimpleXMLElement Object

所以现在你可以看到你的问题的答案是
echo $pxml->dict->array->dict->array->dict[0]->string[0].PHP_EOL;
echo $pxml->dict->array->dict->array->dict[0]->string[1].PHP_EOL;
结果
software-package
http://down.weapp.com/apps/zb/002/43/12/21/58e5bd080ba06228677306a1.ipa
或者在此级别打印所有string项目
foreach ($pxml->dict->array->dict->array->dict as $obj) {
foreach ( $obj->string as $str) {
echo $str . PHP_EOL;
}
}
结果
software-package
http://down.weapp.com/apps/zb/002/43/12/21/58e5bd080ba06228677306a1.ipa
