PHP检查数组数组是否至少有其中之一具有键的搜索值

Question

I have an array contains data about games per day:

"days" => [
    "2019-07-31" => [
        "3" => [
            'id' => 3,
            'type' => normal,
            'teams' => [
                'teamA', 'teamB',
            ],
            'winnerTeam' => 'teamB',
        ],
        "4" => [
            'id' => 4,
            'type' => ranked,
            'teams' => [
                'teamC', 'teamD',
            ],
            'winnerTeam' => 'teamC',
        ],
    ],
    "2019-07-30" => [
        "1" => [
            'id' => 1,
            'type' => normal,
            'teams' => [
                'teamA', 'teamC',
            ],
            'winnerTeam' => 'teamA',
        ],
        "2" => [
            'id' => 2,
            'type' => normal,
            'teams' => [
                'teamB', 'teamD',
            ],
            'winnerTeam' => 'teamC',
        ],
    ],
];

I would like to get data about all ranked games, but before i would like to check if any ranked game happen during these days. Does someone knows more elegant method than foreach of foreach everything? So my goal is to check before getting data if any game['type'] === 'ranked'

You can use array-column and array-count-values to achieve that.

For each day get all the type using array_column and then count it and return if the type "ranked" is set in the return array.

Consider the following:

foreach($arr["days"] as $day => $a) {
    $aaa = array_count_values(array_column($a, "type"));
    if (isset($aaa['ranked'])) 
        echo "Found in $day \n";
}
