PHP ?嵌套数组

Question

我有一个从 Google 地图返回的数组，看起来像这样：

array(4) { 
    ["destination_addresses"]=> array(4) { 
        [0]=> string(19) "Walsall WS2 9PS, UK" 
        [1]=> string(19) "Walsall WS2 9PS, UK" 
        [2]=> string(19) "Walsall WS2 9PS, UK" 
        [3]=> string(26) "Wolverhampton WV10 0QP, UK" 
        } 
    ["origin_addresses"]=> array(1) { 
        [0]=> string(18) "Stone ST15 0FL, UK" 
        }   
    ["rows"]=> array(1) { 
        [0]=> array(1) { 
            ["elements"]=> array(4) { 
                [0]=> array(3) { 
                    ["distance"]=> array(2) { 
                        ["text"]=> string(7) "41.9 km" 
                        ["value"]=> int(41947) 
                    } 
                    ["duration"]=> array(2) { 
                        ["text"]=> string(7) "36 mins" 
                        ["value"]=> int(2134) 
                    } 
                    ["status"]=> string(2) "OK" 
                } 
                [1]=> array(3) { 
                    ["distance"]=> array(2) { 
                        ["text"]=> string(7) "41.9 km" 
                        ["value"]=> int(41947) 
                    } 
                    ["duration"]=> array(2) { 
                        ["text"]=> string(7) "36 mins" 
                        ["value"]=> int(2134) 
                    }
                    ["status"]=> string(2) "OK"
                 } 
                [2]=> array(3) { 
                    ["distance"]=> array(2) { 
                        ["text"]=> string(7) "41.9 km" 
                        ["value"]=> int(41947)
                    } 
                    ["duration"]=> array(2) { 
                        ["text"]=> string(7) "36 mins" 
                        ["value"]=> int(2134) 
                    } 
                    ["status"]=> string(2) "OK"
                } 
                [3]=> array(3) { 
                    ["distance"]=> array(2) { 
                        ["text"]=> string(7) "40.9 km" 
                        ["value"]=> int(40924) 
                    } 
                    ["duration"]=> array(2) { 
                        ["text"]=> string(7) "41 mins" 
                        ["value"]=> int(2458) 
                    } 
                    ["status"]=> string(2) "OK" 
                } 
            } 
        } 
    } 
    ["status"]=> string(2) "OK" 
}

我希望能够运行通过数组，并打印出目的地地址和距离时间值。

这会打印目标地址：

    $length=count($properties);
    for($a=0;$a<$length;$a++)
    {
        echo '</br>Index is ' . $a . ' | id is ' . $index[$a] . ' | destination is ' . $properties["destination_addresses"][$a] . ' | time is ';

    }

但我不知道如何打印其余部分。我一晚上都在用头撞墙！

谢谢期待

要遍历所有这些旅程并打印每个潜在旅程的距离和时间，创建一个 foreach 循环，然后使用 $idx 来处理 muleiple 数组的从属部分

foreach( $destination['destination_addresses'] as $idx => $to ) {
    if ( $destination['rows'][0]['elements'][$idx]['status'] == 'OK' ) {
        echo 'Going from ' . $destination['origin_addresses'][0];
        echo ' To ' . $to;
        echo ' Distance ' . $destination['rows'][0]['elements'][$idx]['distance']['text'];
        echo ' Duration ' . $destination['rows'][0]['elements'][$idx]['duration']['text'];
    } else {
        //whatever you do if the status is not OK
    }
}
