php数字数组选择大于一个数字且小于另一个数字的值并将其保存到一个新数组中
问题描述：
我有一个包含以下数字的数组(动态创建的)
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)
我想通过 >= 和 <= 创建新数组(过滤)，例如新数组包含大于或等于 (>=) 大于 800 且小于或等于 (
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
)
可以不使用 foreach 吗?
is that possible without using foreach?
答
$min = 800;
$max = 1200;
$newNumbers = array_filter(
$numbers,
function ($value) use($min,$max) {
return ($value >= $min && $value <= $max);
}
);
