php从数组中获取值

Question

我在php中有一个数组，从那个数组我希望获得一些像

这样的值

给定的数组就像这样

我希望从此数组中获取类似start_date, adult_travelers, child_travelers, infant_travelers的值，其product_id为963。所以有人可以告诉我如何获得post_id = 963的那些值。任何帮助和建议都会非常明显。

Answer 1

$product_id = 963;
foreach ($prodArr AS $eachArr) {
    if ($eachArr['product_id'] == $product_id) {
        $start_date = $eachArr['variation']['start_date'];
        $adult_travelers = $eachArr['variation']['adults_travelers'];
        $child_travelers = $eachArr['variation']['child_travelers'];
        break;
    }
}

Answer 2

一个简单的foreach可以像Ghost一样正确地完成工作：

Answer 3

foreach ($data AS $array) {

    if($array['data']->post->ID == '963') {

        echo $array['variation']['start_date'];
        echo $array['variation']['adults_travelers'];
        echo $array['variation']['child_travelers'];
    }
}
