PHP dagi guruhlovchi qavslar

Istasangiz, operatsiyalarning ustuvorligini aylana qavslar yordamida belgilashingiz mumkin. Keling, masalan, kodimizni qayta ishlab chiqamiz, avval qo'shish, keyin esa ko'paytirish bajarilsin:

php<?php
  $a = 2 * (2 + 3);
  echo $a; // 10 ni chiqaradi (2 * 5 natijasi)
?>

Qavslar istalgan miqdorda bo'lishi mumkin, hatto bir-biriga ichki ham:

php<?php
  $a = 2 * (2 + 4 * (3 + 1));
  echo $a;
?>

php<?php
  $a = (2 + 3) * (2 + 3);
  echo $a;
?>

php<?php
  $a = (2 + 3) * 2 + 3;
  echo $a;
?>

php<?php
  $a = 2 * (2 + 4 * (3 + 1));
  echo $a;
?>

php<?php
  $a = 2 * 8 / 4;
  echo $a;
?>
