php数组选择大于数字且低于另一数字的值并将其保存到新数组

Question

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?

Answer 1

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

Answer 2

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;
});
