How can I condense the values in an array?

I have an array of elements, I need to change elements at the beginning of an array and I'm using the foreach.

Array
(
    [0] => Array
        (
            [0] => user
            [1] => address
            [2] => detail
            [3] => name
            [4] => family
        )

    [1] => Array
        (
            [0] => user
            [1] => address
        )

    [2] => Array
        (
            [0] => user
            [1] => address
            [2] => detail
            [3] => name
        )

)

I want this output:

Array
(
    [0] => Array
        (
            [0] => user.address.detail.name
            [1] => family
        )

    [1] => Array
        (
            [0] => user
            [1] => address
        )

    [2] => Array
        (
            [0] => user.address.detail
            [1] => name
        )

)

this is my code but it seems it's not working.

    $firstTemp = "";
    foreach ($temps as $row => $temp) {
        if (count($temp) > 2) {
            foreach ($temp as $k => $content) {

                $firstTemp .= $content . '.';
                $endTemp = end($temp);
            }
        }
    }

Is there a better and more concise way to accomplish this?

I made some modification in your snippet to make it work,

$result    = [];
foreach ($temps as $row => $temp) {
    if (count($temp) > 2) {
        // I am taking a slice of the array except for last element and imploding it with `.`
        // then I am fetching the last element of an array
        //  creating an array and pushing it into the result variable
        $result[] = [implode(".", array_slice($temp, 0, count($temp) - 1)), end($temp)];
    }else{
        $result[] = $temp;
    }
}

I am imploding all the elements except last element using array_slice.
end I used to fetch the last element of an array.

Demo.

EDIT 1
One more way to achieve the same,

$result    = [];
foreach ($temps as $row => $temp) {
    if (count($temp) > 2) {
        // except last elements
        $result[] = [implode(".", array_slice($temp, 0, -1)), end($temp)];
    }else{
        $result[] = $temp;
    }
}

Demo.

EDIT 2 

$result    = [];
foreach ($temps as $row => $temp) {
    $result[] = (count($temp) > 2 ? [implode(".", array_slice($temp, 0, -1)), end($temp)] : $temp);
}

Demo.

EDIT 3

$result = array_map(function($temp){
    return (count($temp) > 2 ? [implode(".", array_slice($temp, 0, -1)), end($temp)] : $temp);
},$temps);

Demo.

EDIT 4: Without condition 

$result = array_map(function($temp){
    return [implode(".",array_slice($temp,0,-1)),array_pop($temp)];
},$temps);

EDIT 5

$result = array_map(function($temp){
    return [implode(".",array_slice($temp,0,-1)),end($temp)];
},$temps);

Demo.

Output:

Array
(
    [0] => Array
        (
            [0] => user.address.detail.name
            [1] => family
        )

    [1] => Array
        (
            [0] => user
            [1] => address
        )

    [2] => Array
        (
            [0] => user.address.detail
            [1] => name
        )

)

You can pull the last element and implode() rest of the element from array Like:

$formatted = [];

foreach($temps as $arr) {

    if(count($arr) == 0){
       return;
    }

     $last = array_pop($arr);

    if(count($arr) > 0) //check if array not empty.
       $formatted[] = [implode(".", $arr), $last];
    else
       $formatted[] = [$last];   
}

You can do it without using two foreach structures. For example:

$result = array_map(function (&$temp) {
  $last = array_pop($temp);
  $first = implode('.', $temp);

  return [$first, $last];
}, $temps);

$data = [
    [
        'user',
        'address',
        'detail',
        'name',
        'family',
    ], [
        'user',
        'address',
    ], [
        'user',
        'address',
        'detail',
        'name',
        'family',
    ]
];

$result = array_map(function($item) {
    $last = array_pop($item);

    return [implode('.', $item), $last];
}, $data);
