将数组关联到两个不同的数组并加入它们

Question

我有像这样的关联数组(存储在$ array中):

Array
(
    [0] => Array
        (
            [one] => some text1
            [two] => some paragraph here1.
        )

    [1] => Array
        (
            [one] => some text2
            [two] => some paragraph here2.        
        )

    [2] => Array
        (
            [one] => some text3
            [two] => some paragraph here3.        
        )

    [3] => Array
        (
            [one] => some text4
            [two] => some paragraph here4.        
        )

    [4] => Array
        (
            [one] => some text5
            [two] => some paragraph here5.        
        )

)

现在,我想存储它们的结果,如下所示:

$ first ='some text1,some text2,some text3,some text4,some text5';

$ second ='某段落在这里1.这里有一段2.这里有一段3.这里有一段4.这里有一段5.';

苦苦挣扎我得到了这样的解决方案:

$first= '';
$second = '';
for($i = 0; $i<count($array); $i++){
    $first .= $array[$i]['one'] . ($i == count($array) - 1 ? '': ',');
    $second .= $array[$i]['two'];
}

echo $first;
echo $second;

但我希望已经有一个内置的php函数将关联数组拆分为两个不同的数组.

对于PHP版本> 5.5.你可以简单的使用array_column以及implode功能等作为

echo $first = implode(',',array_column($your_array,'one'));
echo $second = implode(',',array_column($your_array,'two'));

对于较低版本,您可以array_map像使用一样

echo $first = implode(',',array_map(function($v){ return $v['one'];} ,$your_array));
echo $second = implode(',',array_map(function($v){ return $v['two'];},$your_array));
