Php 如何使用simpleXML将树解析为嵌套数组？
我正在编写一个PHP脚本，该脚本从第三方API（订单管理系统）请求xml数据：客户订单，由于主API调用不能正常工作（而且他们也不打算修复），因此我获得所需数据的唯一方法是使用一个调用，该调用将其作为jstree返回（html:ul LIA）格式如下：Php 如何使用simpleXML将树解析为嵌套数组？,php,arrays,parsing,xml-parsing,simplexml,Php,Arrays,Parsing,Xml Parsing,Simplexml,我正在编写一个PHP脚本，该脚本从第三方API（订单管理系统）请求xml数据：客户订单，由于主API调用不能正常工作（而且他们也不打算修复），因此我获得所需数据的唯一方法是使用一个调用，该调用将其作为jstree返回（html:ul LIA）格式如下： <ul> <li> <a>Order</a> <ul> <li> <a>Id</a&

$output[]=$output[$li->a]=谢谢，这里的主要变化只是处理XML的循环
foreach ($ul->li as $li) {
$newLayer = (isset($li->ul)) ? ul_to_array($li->ul) : trim((string) $li);
$output[ (string)$li->a ] = $newLayer[''] ?? $newLayer;
}
（string）$li->a$newLayer[“”]$newLayer''Array
