Get current date given a timezone in PHP

Question

I want to get todays date given a time zone in Paul Eggert format America New York  in PHP

User · Answer

Set the default time zone first and get the date then, the date will be in the time zone you specify :

<?php 
 date_default_timezone_set('America/New_York');
 $date= date('m-d-Y') ;
 ?>

The other answers set the timezone for all dates in your system  This doesn t always work well if you want to support multiple timezones for your users    Here s the short version    lt  php  date   new DateTime  now   new DateTimeZone  America New York      echo  date- gt format  Y-m-d H i s      Works in PHP    5 2 0  List of supported timezones  php net manual en timezones php    Here s a version with an existing time and setting timezone by a user setting   lt  php   usersTimezone    America New York    date   new DateTime   Thu  31 Mar 2011 02 05 59 GMT   new DateTimeZone  usersTimezone     echo  date- gt format  Y-m-d H i s        Here is a more verbose version to show the process a little more clearly    lt  php     Date for a specific date time   date   new DateTime  Thu  31 Mar 2011 02 05 59 GMT        Output date  as-is  echo  date- gt format  l  F j Y g i s A             Output line break  for testing  echo   n lt br   gt  n       Example user timezone  to show it can be used dynamically   usersTimezone    America New York       Convert timezone  tz   new DateTimeZone  usersTimezone    date- gt setTimeZone  tz       Output date after  echo  date- gt format  l  F j Y g i s A        Libraries   Carbon     A very popular date library  Chronos     A drop-in replacement for Carbon focused on immutability  See below on why that s important  jenssegers date     An extension of Carbon that adds multi-language support    I m sure there are a number of other libraries available  but these are a few I m familiar with     Bonus Lesson  Immutable Date Objects  While you re here  let me save you some future headache  Let s say you want to calculate 1 week from today and 2 weeks from today  You might write some code like    lt  php     Create a datetime  now  in this case 2017-Feb-11   today   new DateTime     echo  today- gt format  Y-m-d       n lt br gt    echo  --- n lt br gt      oneWeekFromToday    today- gt add DateInterval  createFromDateString  7 days      twoWeeksFromToday    today- gt add DateInterval  createFromDateString  14 days      echo  today- gt format  Y-m-d       n lt br gt    echo  oneWeekFromToday- gt format  Y-m-d       n lt br gt    echo  twoWeeksFromToday- gt format  Y-m-d       n lt br gt    echo   n lt br gt      The output   2017-02-11  ---  2017-03-04  2017-03-04  2017-03-04   Hmmmm    That s not quite what we wanted  Modifying a traditional DateTime object in PHP not only returns the updated date but modifies the original object as well   This is where DateTimeImmutable comes in    today   new DateTimeImmutable     echo  today- gt format  Y-m-d       n lt br gt    echo  --- n lt br gt      oneWeekFromToday    today- gt add DateInterval  createFromDateString  7 days      twoWeeksFromToday    today- gt add DateInterval  createFromDateString  14 days      echo  today- gt format  Y-m-d       n lt br gt    echo  oneWeekFromToday- gt format  Y-m-d       n lt br gt    echo  twoWeeksFromToday- gt format  Y-m-d       n lt br gt      The output   2017-02-11  ---  2017-02-11  2017-02-18  2017-02-25    In this second example  we get the dates we expected back  By using DateTimeImmutable instead of DateTime  we prevent accidental state mutations and prevent potential bugs

If you have access to PHP 5 3  the intl extension is very nice for doing things like this   Here s an example from the manual    fmt   new IntlDateFormatter   en US   IntlDateFormatter  FULL  IntlDateFormatter  FULL       America Los Angeles  IntlDateFormatter  GREGORIAN      fmt- gt format 0     0 for current time date   In your case  you can do    fmt   new IntlDateFormatter   en US   IntlDateFormatter  FULL  IntlDateFormatter  FULL           America New York      fmt- gt format  datetime     where  datetime may be a DateTime object  an integer representing a Unix timestamp value  seconds since epoch  UTC  or an array in the format output by localtime       As you can set a Timezone such as America New York  this is much better than using a GMT or UTC offset  as this takes into account the day light savings periods as well   Finaly  as the intl extension uses ICU data  which contains a lot of very useful features when it comes to creating your own date time formats
