Fast Tip: The way to Get the Present Date in PHP — SitePoint | Digital Noch

PHP gives a number of features and lessons for working with dates and occasions. On this article, we’ll take a look at the other ways to get the present date and time in PHP and talk about some extra issues when working with time in PHP.

Utilizing the date Perform

The date() perform is an easy and easy-to-use perform for getting the present date and time. To get the present date, you need to use the date() perform with a format string that specifies the specified date format. For instance:

<?php
$currentDate = date('Y-m-d');
echo $currentDate;

It will output the present date within the format YYYY-MM-DD, similar to 2023-03-14. We are able to specify a distinct format by utilizing a distinct format string as the primary argument to the date() perform. For instance:

<?php
$currentDate = date('l, F j, Y');
echo $currentDate;

It will output the date on this format: the total title of the present day of the week, the total title of the month, the numeric day of the month, and the four-digit illustration of the 12 months, similar to Tuesday, March 14, 2023.

You will discover a listing of obtainable format strings within the PHP documentation.

By default, the date() perform makes use of the server’s native time zone. If you’ll want to work with a distinct time zone, you need to use the date_default_timezone_set perform to set the default time zone earlier than calling the date() perform.

Utilizing the time and gmdate Features

One other method to get the present date and time is to make use of the time() perform to get the present timestamp (the variety of seconds for the reason that Unix epoch, January 1, 1970 00:00:00 UTC), after which use the gmdate() perform to format the timestamp as a date string. For instance:

<?php
$timestamp = time();
$currentDate = gmdate('Y-m-d', $timestamp);
echo $currentDate;

It will output the present date within the format YYYY-MM-DD, similar to 2023-03-14. We are able to specify a distinct format by utilizing a distinct format string because the second argument to the gmdate() perform.

The gmdate() perform is just like the date() perform, but it surely at all times makes use of the UTC time zone. This may be helpful if you’ll want to work with dates and occasions in a constant time zone, whatever the server’s native time zone.

Utilizing the DateTime Class

The DateTime class gives an object-oriented interface for working with dates and occasions. To get the present date and time, you need to use the DateTime() constructor with the now argument. You may then use the format() technique to format the date and time as a string. For instance:

<?php
$currentDateTime = new DateTime('now');
$currentDate = $currentDateTime->format('Y-m-d');
echo $currentDate;

It will output the present date within the format YYYY-MM-DD, similar to 2023-03-14. You may specify a distinct format by utilizing a distinct format string because the argument to the format() technique. For instance:

<?php
$currentDateTime = new DateTime('now');
$currentDate = $currentDateTime->format('l, F j, Y');
echo $currentDate;

It will output the date in the identical format as earlier: the total title of the present day of the week, the total title of the month, the numeric day of the month, and the four-digit illustration of the 12 months, similar to Tuesday, March 14, 2023.

By default, the DateTime() constructor makes use of the server’s native time zone. If you’ll want to work with a distinct time zone, you possibly can go a time zone string or a DateTimeZone object because the second argument to the constructor, or use the setTimezone() technique to set the time zone for an current DateTime object.

$currentDateTime = new DateTime('now', new DateTimeZone('UTC'));

$currentDateTime = new DateTime('now');
$currentDateTime->setTimezone(new DateTimeZone('UTC'));

The DateTime class gives a number of different helpful strategies for working with dates and occasions, similar to add(), sub(), and diff(), which let you carry out arithmetic with dates and occasions, and createFromFormat(), which lets you create a DateTime object from a customized date and time format. You will discover extra details about these strategies and others within the PHP documentation right here.

Further Concerns when Working with Dates in PHP

Listed here are a number of extra issues we would wish to contemplate when working with dates in PHP:

  • Time zones. By default, the date(), gmdate(), and DateTime() features use the server’s native time zone. If we have to work with a distinct time zone, we will use the date_default_timezone_set() perform to set the default time zone, or use the DateTimeZone class to create a time zone object and go it to the DateTime() constructor or the setTimezone() technique.

  • Daylight saving time. Relying in your location, the time of day might change twice a 12 months as a consequence of daylight saving time. This could trigger points with time-based features, similar to strtotime(), which can not accurately deal with the change in time. To keep away from these points, you need to use the DateTime class, which gives built-in assist for daylight saving time.

  • Localization. If you’ll want to show dates and occasions in a selected language or format, you need to use the setlocale() perform to set the present locale, and the strftime() perform to format dates and occasions in line with the present locale. You will discover extra details about localization in PHP within the documentation right here.

Conclusion

In conclusion, there are a number of methods to get the present date and time in PHP. Regardless of which technique you select, it’s vital to think about components similar to time zones, daylight saving time, and localization when working with dates and occasions in PHP. By taking these components under consideration, you possibly can make sure that your code precisely displays the present date and time and that your date and time-based performance works as anticipated.
