如何在php中获取多维数组中的所有键?

Array
(
    [0] => Array
        (
            [name] => A
            [id] => 1
            [phone] => 416-23-55
            [Base] => Array
                (
                    [city] => toronto
                )

            [EBase] => Array
                (
                    [city] => North York                
                )

            [Qty] => 1
        )

(
    [1] => Array
        (
            [name] => A
            [id] => 1
            [phone] => 416-53-66
            [Base] => Array
                (
                    [city] => qing
                )

            [EBase] => Array
                (
                    [city] => chong                
                )

            [Qty] => 2
        )

)

How can I get the all the key value with the format "0, name, id, phone, Base, city, Ebase, Qty"?

如何使用“0,name, id, phone, Base, city, Ebase, Qty”格式获取所有键值?

Thank you!

谢谢你！

Try this

试试这个

function array_keys_multi(array $array)
{
    $keys = array();

    foreach ($array as $key => $value) {
        $keys[] = $key;

        if (is_array($value)) {
            $keys = array_merge($keys, array_keys_multi($value));
        }
    }

    return $keys;
}

If you don't know what the size of the array is going to be, use a recursive function with a foreach loop that calls itself if each $val is an array. If you do know the size, then just foreach through each dimension and record the keys from each.

如果不知道数组的大小，可以使用一个带有foreach循环的递归函数，如果每个$val都是一个数组，那么这个循环就会调用自己。如果您确实知道大小，那么只需对每个维度进行foreach并记录每个维度的键。

Something like this:

是这样的:

<?php
function getKeysMultidimensional(array $array) 
{
    $keys = array();
    foreach($array as $key => $value)
    {
        $keys[] = $key;
        if( is_array($value) ) { 
            $keys = array_merge($keys, getKeysMultidimensional($value));
        }
    }

    return $keys;

}
