Every this perfect but I don't want to usename for key:
这一切都很完美，但我不想使用名字作为密钥：
Array
(
[tom] => Array
(
...
)
[jack] => Array
(

)
)
Any idea how to change array key like this for better reading results:
知道如何更改这样的数组键以获得更好的读取结果：
Array
(
[0] => Array
(
...
)
[1] => Array
(
...

Use array_values($array) function will return all values in an array with numerical index. reference: http://php.net/manual/en/function.array-values.php
使用array_values（$ array）函数将返回具有数字索引的数组中的所有值。参考：http：//php.net/manual/en/function.array-values.php
example:
例：
<?php
$array = array("size" => "XL", "color" => "gold");
print_r(array_values($array));
?>
output:
输出：
Array
(
[0] => XL
[1] => gold
)

Don't set it in your foreach:
不要在你的foreach中设置它：
foreach ($GetArrayOfEngagementPerInfluencer as $item) {
$grouped[][] = $item;
}

How about you use $key as:
你怎么用$ key作为：
foreach ($GetArrayOfEngagementPerInfluencer as $key=>$item) {
$grouped[$key][] = $item;
}
