感谢您的帮助。您应该能够执行以下操作：
function displayTree($nodes) {
echo '<ul>';
foreach ($nodes->getChildren() as $childNode) { // $childNode is a BaobabNode Object
echo '<li>';
echo $childNode->getName(); // or equivalent method to get the name
if (count($childNode->children) > 0) {
displayTree($childNode->children);
}
echo '</li>';
}
echo '</ul>';
}
函数显示树（$nodes）{
回声“”；
foreach（$nodes->getChildren（）作为$childNode）{/$childNode是一个baobabonode对象
回音“- ”；
echo$childNode->getName（）；//或获取名称的等效方法
如果（计数（$childNode->children）>0）{
displayTree（$childNode->children）；
}
回音“
”；
}
回声“
”；
}
