PHP siklda massivni o'zgartirish
Bizda quyidagi sonlar massivi berilgan bo'lsin:
<?php
$arr = [1, 2, 3, 4, 5];
?>
Keling, ushbu massivning har bir elementini ikki baravar oshiramiz:
<?php
$arr = [1, 2, 3, 4, 5];
$arr[0] = $arr[0] * 2;
$arr[1] = $arr[1] * 2;
$arr[2] = $arr[2] * 2;
$arr[3] = $arr[3] * 2;
$arr[4] = $arr[4] * 2;
var_dump($arr); // [2, 4, 6, 8, 10] ni chiqaradi
?>
Endi xuddi shu narsani siklda bajaramiz:
<?php
$arr = [1, 2, 3, 4, 5];
$length = count($arr);
for ($i = 0; $i < $length; $i++) {
$arr[$i] = $arr[$i] * 2;
}
var_dump($arr); // [2, 4, 6, 8, 10] ni chiqaradi
?>
Sonlar massivi berilgan. Ushbu massivni sikl yordamida qayta ishlang va har bir elementni kvadratga ko'taring.
