我试图通过用户名重新组合我的数组，我写了这段代码：

$grouped = array();
foreach ($GetArrayOfEngagementPerInfluencer as $item) {
    $grouped[$item->username][] = $item;
}
p($grouped);

得到了这个结果：

这一切都很完美，但我不想使用名字作为密钥：

Array
    (
        [tom] => Array
            (
                ...
            )
        [jack] => Array
            (
                ...
            )    
    )

知道如何更改这样的数组键以获得更好的阅读结果：

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

Answer 1

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

示例：

<?php
    $array = array("size" => "XL", "color" => "gold");
    print_r(array_values($array));
?>

输出：

Array
(
    [0] => XL
    [1] => gold
)

Answer 2

不要在你的foreach中设置它：

foreach ($GetArrayOfEngagementPerInfluencer as $item) {
    $grouped[][] = $item;
}

Answer 3

您如何使用$key：

foreach ($GetArrayOfEngagementPerInfluencer as $key=>$item) {
    $grouped[$key][] = $item;
}
