如何通过键从数组中返回某些数据

I was looking for a way of solving a problem of returning keys and data from an a array.

The keys are 7,8,9,10 and "size","atime","mtime","ctime" from an array returned by the stat() function.

function returnDataByKeys($keys,$array){

    $tmp = array();
    foreach($keys as $keyValue)
        $tmp[$keyValue] = $array[$keyValue];

    return $tmp;
}

As for my question, I am looking for a more array_* function way of extracting the desired keys & values as a block with the keys preserved.

With all the other array_* functions I have seen, I don't see one that allows you to put in key data and return only those keys if found in an array.

If I'm understanding your question correctly, it's as simple as this:

array_intersect_key($array, array_flip(array('size', 'atime', ..)))
