php - 如何从php中的多维数组中获取父数组索引

Question

我有一个数组 $arr。

当我打印它时，它显示的结果如下。

Array
(
    [0] => Array
        (
            [name] => homeandgarden-Control Type
            [1] => Array

                    [0] => product
                )

        )

    [1] => Array

                (
                    [0] => product
                )

        )
)

我有一个变量 $categ.For example $categ = " homeandgardenairconditioner-Type " 那么我想知道 " name " 是 " homeandgardenairconditioner-Type "的父数组的索引

即 --- o/p 应该是 9

如何获得这个索引。请帮我

谢谢

我想你正在寻找这个：

function getIndex($name, $array){
    foreach($array as $key => $value){
        if(is_array($value) && $value['name'] == $name)
              return $key;
    }
    return null;
}
