array_values()清除不需要的键可以通过在结果数组中推送引用变量来避免。这是一种更直接的方法。
我假设“资源名”是标识数据集唯一性的可靠方法。Declare通过这个标识符引用变量。
如果以前没有遇到过标识符，则将action值转换为一个单独元素数组，定义引用变量的数据，然后推入结果数组。如果以前遇到过标识符，则只需将新的action值推入引用的action子数组。
产品编号：（Demo）

$result = [];
foreach ($array as $key => $sets) {
    foreach ($sets as $set) {
        $id = $set['resource']['name'];
        if (!isset($ref[$id])) {
            $set['action'] = (array) $set['action'];
            $ref[$id] = $set;
            $result[$key][] = &$ref[$id];
        } else {
            $ref[$id]['action'][] = $set['action'];
        }
    }
}
var_export($result);

或者，如果您只想改变输入数组而不生成新数组，则调整引用以指向第一个遇到的给定name值集合的action子数组。
代码：（Demo）

foreach ($array as $key => &$sets) {
    foreach ($sets as $i => &$set) {
        $id = $set['resource']['name'];
        if (!isset($ref[$id])) {
            $set['action'] = (array) $set['action'];
            $ref[$id] = &$set['action'];
        } else {
            $ref[$id][] = $set['action'];
            unset($array[$key][$i]);
        }
    }
}
var_export($array);

要实现所需的数据结构，可以循环遍历原始数组，并使用临时关联数组按**“name”**字段对元素进行分组。然后可以从这个临时数组创建所需的结构。下面是一个PHP代码示例：

$outputArray = [];

foreach ($inputArray as $key => $items) {
    $tempArray = [];

    foreach ($items as $item) {
        $name = $item['resource']['name'];

        if (!isset($tempArray[$name])) {
            $tempArray[$name] = [
                'foo' => $item['foo'],
                'action' => [],
                'resource' => $item['resource'],
            ];
        }

        $tempArray[$name]['action'][] = $item['action'];
    }

    $outputArray[$key] = array_values($tempArray);
}
echo "<pre>";
print_r($outputArray);

这将在$outputArray中为您提供给予所需的数据结构。
