I want to put a copyright notice in the footer of a web site, but I think it's incredibly tacky for the year to be outdated.

How would I make the year update automatically with PHP 4 or PHP 5?

echo date("Y");doub1ejack
I got a warning using that. Added date_default_timezone_set('UTC'); to avoid getting the warning. ('UTC+1' doesn't work... can't tell you much as just starting with PHP). Probably there's some way to configure PHP to avoid throwing the warnings though (in some config file like php.ini).justin
@justin This means you haven't set the default timezone and PHP doesn't like that. You can either set the default timezone in the php.ini file with something like date.timezone = "America/Los_Angeles" or you can set it at the beginning of your code with something like date_default_timezone_set( "America/Los_Angeles" ).Joshua Pinter
NOTE: The year in a copyright notice does not really have much legal value, but is usually added to aid people who want to know whether the copyright still applies. As such it is supposed to be the year the work was published. Just using the current year really makes no sense whatsoever... However I have seen it done countless times.Stijn de Witt
I'd personally argue that it has become a web convention, so although you are technically correct, it's not what people expect. The fact remains that although having, i.e. "Copyright 2007, all rights reserved' emblazoned on the footer of a page containing an article written in 2007 is technically correct, visitors to the site are likely to assume that the site has been abandoned. Even large corporations with teams of lawyers still stamp their web pages with the current year, even if it's '2007-2015'.Nathan Hornby

You can use either date or strftime. In this case I'd say it doesn't matter as a year is a year, no matter what (unless there's a locale that formats the year differently?)

For example:

<?php echo date("Y"); ?>

On a side note, when formatting dates in PHP it matters when you want to format your date in a different locale than your default. If so, you have to use setlocale and strftime. According to the php manual on date:

To format dates in other languages, you should use the setlocale() and strftime() functions instead of date().

From this point of view, I think it would be best to use strftime as much as possible, if you even have a remote possibility of having to localize your application. If that's not an issue, pick the one you like best.

My super lazy version of showing a copyright line, that automatically stays updated:

&copy; <?php 
$copyYear = 2008; 
$curYear = date('Y'); 
echo $copyYear . (($copyYear != $curYear) ? '-' . $curYear : '');
?> Me, Inc.

This year (2008), it will say:

© 2008 Me, Inc.

Next year, it will say:

© 2008-2009 Me, Inc.

and forever stay updated with the current year.


Or (PHP 5.3.0+) a compact way to do it using an anonymous function so you don't have variables leaking out and don't repeat code/constants:

&copy; 
<?php call_user_func(function($y){$c=date('Y');echo $y.(($y!=$c)?'-'.$c:'');}, 2008); ?> 
Me, Inc.

With PHP heading in a more object-oriented direction, I'm surprised nobody here has referenced the built-in DateTime class:

$now = new DateTime();
$year = $now->format("Y");

or one-liner with class member access on instantiation (php>=5.4):

$year = (new DateTime)->format("Y");

strftime("%Y");

I love strftime. It's a great function for grabbing/recombining chunks of dates/times.

Plus it respects locale settings which the date function doesn't do.

This one gives you the local time:

$year = date('Y'); // 2008

And this one UTC:

$year = gmdate('Y'); // 2008

Here's what I do:

<?php echo date("d-m-Y") ?>

below is a bit of explanation of what it does:

d = day
m = month
Y = year

Y will gives you four digit (e.g. 1990) and y for two digit (e.g. 90)

For 4 digit representation:

<?php echo date('Y'); ?>

2 digit representation:

<?php echo date('y'); ?>

Check the php documentation for more info: https://secure.php.net/manual/en/function.date.php

echo date('Y') gives you current year, and this will update automatically since date() give us the current date.

use a PHP function which is just called date().

It takes the current date and then you provide a format to it

and the format is just going to be Y. Capital Y is going to be a four digit year.

<?php echo date("Y"); ?>

If your server supports Short Tags, or you use PHP 5.4, you can use:

<?=date("Y")?>

Just write:

date("Y") // A full numeric representation of a year, 4 digits
          // Examples: 1999 or 2003

Or:

date("y"); // A two digit representation of a year     Examples: 99 or 03

And 'echo' this value...

For up to php 5.4+

<?php
    $current= new \DateTime();
    $future = new \DateTime('+ 1 years');

    echo $current->format('Y'); 
    //For 4 digit ('Y') for 2 digit ('y')
?>

Or you can use it with one line

$year = (new DateTime)->format("Y");

If you wanna increase or decrease the year another method; add modify line like below.

<?PHP 
  $now   = new DateTime;
  $now->modify('-1 years'); //or +1 or +5 years 
  echo $now->format('Y');
  //and here again For 4 digit ('Y') for 2 digit ('y')
?>

use a PHP date() function.

BTW... there are a few proper ways how to display site copyright. Some people have tendency to make things redundant i.e.: Copyright © have both the same meaning. The important copyright parts are:

**Symbol, Year, Author/Owner and Rights statement.** 

Using PHP + HTML:

<p id='copyright'>&copy; <?php echo date("Y"); ?> Company Name All Rights Reserved</p>

or

<p id='copyright'>&copy; <?php echo "2010-".date("Y"); ?> Company Name All Rights Reserved</p

Get full Year used:

 <?php 
    echo $curr_year = date('Y'); // it will display full year ex. 2017
?>

Or get only two digit of year used like this:

 <?php 
    echo $curr_year = date('y'); // it will display short 2 digit year ex. 17
?>

best shortcode for this section:

<?= date("Y"); ?>

My way to show the copyright, That keeps on updating automatically

<p class="text-muted credit">Copyright &copy;
    <?php
        $copyYear = 2017; // Set your website start date
        $curYear = date('Y'); // Keeps the second year updated
        echo $copyYear . (($copyYear != $curYear) ? '-' . $curYear : '');
    ?> 
</p>    

It will output the results as

copyright @ 2017   //if $copyYear is 2017 
copyright @ 2017-201x    //if $copyYear is not equal to Current Year.

in my case the copyright notice in the footer of a wordpress web site needed updating.

thought simple, but involved a step or more thann anticipated.

  1. Open footer.php in your theme's folder.

  2. Locate copyright text, expected this to be all hard coded but found:

    <div id="copyright">
        <?php the_field('copyright_disclaimer', 'options'); ?>
    </div>
    
  3. Now we know the year is written somewhere in WordPress admin so locate that to delete the year written text. In WP-Admin, go to Options on the left main admin menu:

    enter image description here Then on next page go to the tab Disclaimers:

    enter image description here and near the top you will find Copyright year:

    enter image description here DELETE the © symbol + year + the empty space following the year, then save your page with Update button at top-right of page.

  4. With text version of year now delete, we can go and add our year that updates automatically with PHP. Go back to chunk of code in STEP 2 found in footer.php and update that to this:

    <div id="copyright">
        &copy;<?php echo date("Y"); ?> <?php the_field('copyright_disclaimer', 'options'); ?>
    </div>
    
  5. Done! Just need to test to ensure changes have taken effect as expected.

this might not be the same case for many, however we've come across this pattern among quite a number of our client sites and thought it would be best to document here.

To get the current year using PHP’s date function, you can pass in the “Y” format character like so:

//Getting the current year using //PHP's date function.

$year = date("Y");
echo $year;

//Getting the current year using //PHP's date function.

$year = date("Y");
echo $year;

The example above will print out the full 4-digit representation of the current year.

If you only want to retrieve the 2-digit format, then you can use the lowercase “y” format character:

$year = date("y"); echo $year; 1 2 $year = date("y"); echo $year; The snippet above will print out 20 instead of 2020, or 19 instead of 2019, etc.

For more pricise in second param in date function strtotime return the timestamp passed by param

// This work when you get time as string
echo date('Y', strtotime("now"));

// Get next years
echo date('Y', strtotime("+1 years"));

// 
echo strftime("%Y", strtotime("now"));

With datetime class

echo (new DateTime)->format('Y');

If you are using the Carbon PHP API extension for DateTime, you can achieve it easy:

<?php echo Carbon::now()->year; ?>
