PHP darajaga ko'tarish

Sonni darajaga ko'tarish uchun maxsus ** operatori mavjud. Keling, 10 sonini uchinchi darajaga ko'taramiz:

php<?php
  echo 10 ** 3; // 1000 chiqadi
?>

Keling, o'zgaruvchi qiymatini darajaga ko'taramiz:

php<?php
  $a = 10;
  echo $a ** 3; // 1000 chiqadi
?>

Son ham, daraja ham o'zgaruvchilarda saqlanishi mumkin:

php<?php
  $a = 10;
  $b = 3;
  echo $a ** $b; // 1000 chiqadi
?>
