PHPda cookie-lar orqali sahifa yangilanish hisoblagichi

Keling, sahifa yangilanish hisoblagichini yaratamiz:

php<?php
  if (!isset($_COOKIE['counter'])) { // sahifaga birinchi marta kirish
    setcookie('counter', 1);
    $_COOKIE['counter'] = 1;
  } else {
    setcookie('counter', $_COOKIE['counter'] + 1);
    $_COOKIE['counter'] = $_COOKIE['counter'] + 1;
  }
  
  echo $_COOKIE['counter'];
?>

Kodni ++ operatori yordamida soddalashtirish mumkin:

php<?php
  if (!isset($_COOKIE['counter'])) { // sahifaga birinchi marta kirish
    setcookie('counter', 1);
    $_COOKIE['counter'] = 1;
  } else {
    setcookie('counter', ++$_COOKIE['counter']);
  }
  
  echo $_COOKIE['counter'];
?>
