我的意思是areas-academicas
我正在使用嵌套的foreach，但没有：
foreach ($un as $key => $value)
{
if ( $key === "areas-academicas" )
{
echo "Llave: " . $key . " => ";
//echo $value;
foreach ( $value as $key2 => $value2 )
{
echo "Llave2: " . $key2 . "<br />" . "valor2: " . $value2;
foreach ($value2 as $key3 => $value3)
{
echo "Llave3: " . $key3 . "<br />" . "valor3: " . $value3;
}
}
}
}
获得这些价值观的简单方法是什么？感谢。
答案 0 :(得分：1)
如果我没有弄乱你的筑巢，这应该有效。如果它没有修复foreach内的路径。
$data = array(...); // the array you posted
foreach ($data["areas-academicas"]["data"]["options"] as $area) {
echo $area["title"];
}
底线是你可以从任何级别开始迭代，你不必从顶部开始。
答案 1 :(得分：1)
看看数组，你似乎只对顶层的两个数组感兴趣：
$un["areas-academicas"]
$un["areas-academicas-2"]
然后，您正在寻找这两个下面的嵌套结构中的特定值，数据选项的标题：
$un["areas-academicas"]['data']['options'][....]['title']
您可以通过使用这些数组的统一结构来限制循环的迭代。但是我假设您希望在包含“areas-academicas”的键的顶层数组中循环：
$titles = array();
foreach ($un as $key => $value){
if(strpos($key, 'areas-academicas') == false){ continue; }
foreach($value['data']['options'] as $val){
$titles[] = $val['title'];
}
}
这个循环应该收集来自area-academicas数组的所有选项标题，但是依赖于嵌套结构对于顶层数组中的每个区域实例都是统一的。希望这有帮助
