从关联数组中获取值

Question

我有以下主要数组调用 $m

Array
(
    [0] => Array
        (
            [home] => Home
        )

    [1] => Array
        (
            [contact_us] => Contact Us
        )

    [2] => Array
        (
            [about_us] => About Us
        )

    [3] => Array
        (
            [feedback_form] => Feedback Form
        )

    [4] => Array
        (
            [enquiry_form] => Products
        )

    [5] => Array
        (
            [gallery] => Gallery
        )

)

我有值,例如home,contact_us在数组中存储了$ options,我需要使用$ options数组从主数组中获取名为$ m的值

例如.如果$ options数组的值为home,我需要从主数组中获取值Home($ m)

我的代码如下所示

                    $c = 0;
                    foreach($options as $o){
                        echo $m[$c][$o];
                        ++$c;
                    }

我莫名其妙地无法从主阵列接收值？

Answer 1

我首先转换$m为只有一个级别的更简单的数组:

$new_m = array();
foreach ($m as $item) {
    foreach ($item as $key => $value) {
        $new_m[$key] = $value;
    } 
}

然后你可以使用:

foreach ($options as $o) {
    echo $new_m[$o];
}
