DateTimeImmutable Klassi

DateTimeImmutable klassi DateTime ning o'zgarmas analogidir. U har qanday o'zgartirishda yangi ob'ekt yaratadi, bu uni ishlash uchun ko'proq bashorat qilinadigan va xavfsiz qiladi.

Joriy vaqt momenti

Keling, DateTimeImmutable ob'ektini joriy sana va vaqt bilan yaratamiz:

php<?php
  $date = new DateTimeImmutable();
?>

Aniq sana

Keling, DateTimeImmutable ob'ektini ko'rsatilgan sana bilan yaratamiz:

php<?php
  $date = new DateTimeImmutable('2025-12-31');
?>

Aniq sana va vaqt

Keling, DateTimeImmutable ob'ektini ko'rsatilgan sana va vaqt bilan yaratamiz:

php<?php
  $date = new DateTimeImmutable('2025-12-31 12:59:59');
?>

Chiqishni formatlash

Yaratilgan sanani format usuli yordamida belgilangan formatda chiqarish mumkin. Keling, buni joriy vaqt momenti uchun qilaylik:

php<?php
  $date = new DateTimeImmutable();
  echo $date->format('Y-m-d H:i:s');
?>

Natija (bajarish momentiga qarab o'zgaradi):

php'2025-11-15 14:25:00'

Belgilangan sanani formatlash

Keling, belgilangan sanani formatlaymiz:

php<?php
  $date = new DateTimeImmutable('2025-12-31');
  echo $date->format('d.m.Y');
?>

Kodni bajarish natijasi:

php'31.12.2025'

Interval qo'shish

Sanaga interval qo'shish add usuli orqali amalga oshiriladi:

php<?php
  $date = new DateTimeImmutable('2025-05-15');
  $interval = new DateInterval('P10D'); // 10 kun
  $newDate = $date->add($interval);
  echo $newDate->format('Y-m-d');
?>

Kodni bajarish natijasi:

php'2025-05-25'

Intervalni ayirish

Sanaldan intervalni ayirish sub usuli orqali amalga oshiriladi:

php<?php
  $date = new DateTimeImmutable('2025-05-15');
  $interval = new DateInterval('P1M2D'); // 1 oy va 2 kun
  $newDate = $date->sub($interval);
  echo $newDate->format('Y-m-d');
?>

Kodni bajarish natijasi:

php'2025-04-13'

Yangi sanani o'rnatish

DateTimeImmutable ob'ekti uchun yangi sana o'rnatish mumkin. Bu setDate usuli orqali amalga oshiriladi:

php<?php
  $date = new DateTimeImmutable();
  $newDate = $date->setDate(2024, 12, 31);
  echo $newDate->format('Y-m-d');
?>

Kodni bajarish natijasi:

php'2024-12-31'

Vaqtni o'rnatish

DateTimeImmutable ob'ekti uchun yangi vaqt o'rnatish mumkin. Bu setTime usuli orqali amalga oshiriladi:

php<?php
  $date = new DateTimeImmutable();
  $newDate = $date->setTime(15, 30, 0);
  echo $newDate->format('H:i:s');
?>

Kodni bajarish natijasi:

php'15:30:00'

Sanlarni solishtirish

Sana ob'ektlarini solishtirish mumkin:

php<?php
  $date1 = new DateTimeImmutable('2025-01-01');
  $date2 = new DateTimeImmutable('2025-02-01');
  
  if ($date1 < $date2) {
    echo '+++';
  } else {
    echo '---';
  }
?>

Vaqt mintaqasi bilan ob'ekt yaratish

DateTimeImmutable ob'ektini yaratishda vaqt mintaqasini ko'rsatish mumkin:

php<?php
  $timeZone = new DateTimeZone('Europe/Moscow');
  $date = new DateTimeImmutable('2025-12-31 23:59:59', $timeZone);
  
  echo $date->format('Y-m-d H:i:s e');
?>

Kodni bajarish natijasi:

php'2025-12-31 23:59:59 Europe/Moscow'
