将数组关联到两个不同的数组并加入它们

Question

I have associative arrays like this (stored in $array):

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.        
        )

)

Now, I want to store the result of them like this:

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

$second = 'some paragraph here1. some paragraph here2. some paragraph here3. some paragraph here4. some paragraph here5.';

Struggling a lot I got a solution like this:

$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;

But I hope there's already a built-in php function which split assoc arrays into two different arrays.

For PHP version > 5.5. You can simply use array_column along with implode function like as

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

For lower version you can use array_map like as

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