所有表明我面临阵列爆炸的问题

data.txt内容低于

Peer             Call ID      Duration Recv: Pack  Lost       (     %) Jitter Send: Pack  Lost       (     %) Jitter

3 active SIP channels

PHP代码低于

$heads = [ 'Peer', 0, 0, 'CallId', 0, 'Duration', 'Recv', 0, 'RecvLost', 0, 'RecvPC', 'RJitter', 'Send', 0, 'SendLost', 0, 'SendPC', 'SJitter'];

$data = file('data.txt', FILE_IGNORE_NEW_LINES);
unset($data[0]); // Lose heading line

$list = [];
foreach ($data as $str) {
    $list[] = array_combine($heads, explode(' ',$str));
}

的print_r（$列表）;在这样的事情之下。

Array
(
    [0] => Array
        (
            [Peer] => 139.59.232.196
            [0] => (
            [CallId] => 0bb9262d6a1
            [Duration] => 00:01:12
            [Recv] => 0000003558
            [RecvLost] => 0000000000
            [RecvPC] => 0.00%)
            [RJitter] => 0.0000
            [Send] => 0000001177
            [SendLost] => 0000000000
            [SendPC] => 0.00%)
            [SJitter] => 0.0200
        )

    [1] => Array
        (
            [Peer] => 139.59.232.196
            [0] => (
            [CallId] => 41283499492
            [Duration] => 00:00:00
            [Recv] => 0000000000
            [RecvLost] => 0000000000
            [RecvPC] => 0.00%)
            [RJitter] => 0.0000
            [Send] => 0000000000
            [SendLost] => 0000000000
            [SendPC] => 0.00%)
            [SJitter] => 0.0000
        )

    [2] => Array
        (
            [Peer] => 139.59.232.196
            [0] => (
            [CallId] => 7033a541240
            [Duration] => 00:00:08
            [Recv] => 0000000000
            [RecvLost] => 0000000000
            [RecvPC] => 0.00%)
            [RJitter] => 0.0000
            [Send] => 0000000019
            [SendLost] => 0000000000
            [SendPC] => 0.00%)
            [SJitter] => 0.0000
        )

)

当我打电话给他们时，我必须这样做，$ list [＆＃39; 0＆＃39;] [持续时间]然后它给出了数组0持续时间字段数据，但我希望当我这样打电话时$ list [持续时间]它将为我提供所有数组持续时间数据，如下所示

00:01:12 00:00:00 00:00:08

感谢您的关注......

Answer 1

您需要array_column功能：

$durations = array_column($list, 'Duration');

对于php 较旧而不是5.5，您需要一个简单的foreach。
