PHP: Filtering too hight and too low numbers in array

Question

I have an array like this: 102, 97, 101, 1, 107, 95, 555. I need to exclude numbers, which very differ from other. So array should be: 102, 97, 101, 107, 95. How can I do this in php?

1) Have you tried something 2) What means/define very differ from each other ? — Rizier123

This seems to be unclear did you defined the list of array that need to be excluded — Narendrasingh Sisodia

function getAverageArray($min, array $arr){
    $arr2 = array($arr[0]);
    foreach(array_slice($arr,1) as $val)
        if ($val - $arr[0] < $min && $arr[0] - $val < $min)
            $arr2[] = $val;
    return $arr2;
}

//the minimum difference necessary
$min = 90;
$arr = array(102, 97, 101, 1, 107, 95, 555);

//Array ( [0] => 102 [2] => 97 [3] => 101 [4] => 107 [5] => 95 )
print_r(getAverageArray($min,$arr));

These code work incorrect if the first number much higher then other. For example: (999, 102, 97, 101, 1, 107, 95) -> (999)

Well yes basically or you use the first key or you pass the average number, you could even compute them all...

That's possible but you have to set the threshold.

get the average of all the values
exclude values whose `abs(value-avergage) > your_threshold``
