我有一个数组$ arr。

当我打印此文件时,它显示如下结果。

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

        )

    [1] => Array
        (
            [name] => homeandgarden-Depth
            [1] => Array
                (

                )

        )

                    [choose_from_most_used] => 
                )

            [1] => Array
                (
                    [0] => product
                )

        )
)

并且我有一个变量$ categ。例如$ categ =“ homeandgardenairconditioner-Type”然后我想知道其“ name”为“ homeandgardenairconditioner-Type”] >>的父数组的索引

即--- o / p应该为9

如何获取此索引。请帮助我

谢谢

我有一个数组$ arr。当我打印此文件时,结果显示如下。 Array([0] => Array([name] => homeandgarden-Control Type [1] => Array ...
