I have one array(dynamically created) that contains the following numbers

$numbers = array (200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 12000, 14000, 15000, 16000, 18000, 20000, 21000, 24000, 25000, 27000, 30000, 35000, 40000, 45000, 50000, 60000, 70000, 75000, 80000, 90000, 100000, 105000, 120000, 135000, 140000, 150000, 160000, 180000, 200000, 250000, 300000, 350000, 400000, 450000, 500000, 600000, 700000, 800000, 900000, 1000000)

I want to create new array (filtered) by >= and <= for example the new array to contains numbers greater or equal(>=) than 800 and lower or equal(<=) than 1600

New Array
(
    [0] => 800
    [1] => 1000
    [2] => 1200
    [3] => 1400
    [4] => 1600
)

is that possible without using foreach?

array_filter() with a callback –  Mark Baker Apr 2 '13 at 23:13
 
^ array_filter($numbers, function($n){ return $n >= 800 && $n <= 1600 } –  elclanrs Apr 2 '13 at 23:14

$min = 800;
$max = 1200;
$newNumbers = array_filter(
    $numbers,
    function ($value) use($min,$max) {
        return ($value >= $min && $value <= $max);
    }
);

You are looking for array_filter http://php.net/manual/en/function.array-filter.php

A good example of use would be:

array_filter($numbers, function($n){ 
    return $n >= 800 && $n <= 1600 });
