Question

我有数组$ devices，$ port

print_r($devices);
Array(
[0] => cisco1
[1] => cisco2
 )

print_r($port);
Array
(
[0] => Port1/1/1
[1] => Port1/1/10
[2] => Port1/1/11
)

我想创建一个数组$ devlist，它将是这样的：

Array(

[cisco1] =>Port1/1/1
           Port1/1/10
           Port1/1/11

[cisco2] =>Port2/1/1
           Port2/1/10
           Port2/1/11

)

我的观点是每个设备中都有一系列设备（$ devices）和端口阵列。为$ device数组中的每个设备新创建 $ port 数组。

到目前为止我尝试了什么：

foreach ($devices as $value)
{
$port=();
//iam polling the respective device and getting a list of ports available for that device in array **$port**

array_push($devices[$value], $port);
}

此方法生成错误“array_push（）期望参数1为数组，null为”

请原谅我，如果这似乎是一个简单的问题becoz我刚接触php和脚本:(

Answer 1

你想要这样的东西吗？如果是这样，我不明白为什么，当你可以使用每个$ device的$ ports值时？

$devices = array
(
    'cisco1', 'cisco2'
);

$ports = array 
(
    'Port1/1/1',
    'Port1/1/10',
    'Port1/1/11'
);

$dev_list = array();

foreach ($devices as $device) 
{
    $dev_list[$device] = array();

    foreach ($ports as $port) 
    {
        array_push($dev_list[$device], $port);
    }
}

echo '<pre>';
print_r($dev_list);
echo '</pre>';

Array
(
    [cisco1] => Array
        (
            [0] => Port1/1/1
            [1] => Port1/1/10
            [2] => Port1/1/11
        )

    [cisco2] => Array
        (
            [0] => Port1/1/1
            [1] => Port1/1/10
            [2] => Port1/1/11
        )

)

Answer 2

您可以使用foreach或for循环，但主要的是您必须使用variable variables。

解决方案一：

$devlist = array();
foreach($devices as $key => $device){
$devlist[$device] = ${"port".($key+1)};
}

解决方案二：

$devlist = array();
$size = sizeof($devices);
for($i = 0; $i < $size; $i++){
$devlist[$devices[$i]] = ${"port".($i+1)};
}

Answer 3

如果我理解你的问题，你想要这样的事情：

$arr = array
(
    'cisco1' => array 
    (
        'Port1/1/1', 
        'Port1/1/10',
        'Port1/1/11'
    ),
    'cisco2' => array
    (
        'Port1/1/1', 
        'Port1/1/10',
        'Port1/1/11'
    )
);

foreach($arr as $key => $value) // use the foreach-loop like this to get both keys and values
{
    echo "$key: <br />-" . implode('<br />-', $value) . '<br /><br />';
}

打印：

cisco1: 
-Port1/1/1
-Port1/1/10
-Port1/1/11

cisco2: 
-Port1/1/1
-Port1/1/10
-Port1/1/11

Answer 4

试试这个：

    $devlist = array();
    foreach ($devices as $value)
    {
            $port=();
            //iam polling the respective device and getting a list of ports available for that device in array **$port**

            $devlist[$value] = $port;
    }

如何创建一个关联数组，其中包含数组中的元素作为键，并使用数组作为相应的值？
