I want to put a copyright notice in the footer of a web site, but I think it's incredibly tacky for the year to be outdated.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

php echo date("M d Y", strtotime("-1 year")); ?> Show activity on this post. <? php echo date("Y",strtotime("-1 year")); //last year "2021" echo date("Y"); //current year "2022" echo date("Y-m-d",strtotime("-1 year")); //one year ago "2021-03-31" echo date("Y"); //current date "2022-03-31" ?>
Answer: Use the PHP date() Function You can simply use the PHP date() function to get the current data and time in various format, for example, date('d-m-y h:i:s') , date('d/m/y H:i:s') , and so on.
$year = date('Y') - 1; // Get current year and subtract 1 $start = mktime(0, 0, 0, 1, 1, $year); $end = mktime(0, 0, 0, 12, 31, $year);
$date = date("yyyy-mm-dd", strtotime(now));
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.
