How to display a certain number of elements by condition using foreach?

Question

JavaScript

There is an array, it is displayed through foreach, it is required to display not the entire array but the first 2 elements, in total we will offer 5 of them in the array. I would like to see some example on this topic. Thanks in advance))

Answer 1

The cycle then works, but with the logic of calculating the degree of the problem. Look closely at the differences:

var number = 2;
var power = 10;
var result = 1;

for(i = 0; i < power; i = i + 1){
    result = result*number;
}
console.log(result);

Answer 2

$i = 1;
foreach($arr as $item) {
    if ($i > 2) break;
    echo $item;
    $i++;
}
