我有一个变量$ categ。例如$ categ =“ homeandgardenairconditioner-Type ” 那么我想知道“名称”是“ homeandgardenairconditioner-Type ”的父数组的索引
即--- o / p应为9
如何获取此索引。请帮帮我

答案 0 :(得分：7)
我认为你正在寻找这个：
function getIndex($name, $array){
foreach($array as $key => $value){
if(is_array($value) && $value['name'] == $name)
return $key;
}
return null;
}
