PHP Pretty Date

10 Feb 2008 Read in about 1 minute

This class is pretty much a direct port of John Resig’s JavaScript Pretty Date to PHP 5. A few notes:

  • Requires PHP >= 5.10, due to the usage of PHP’s new DateTimeclass.
  • The new DateTime object parses strings using PHP’s strtotime, so you don’t need to pass in an ISO8601 formatted date, as in JavaScript Pretty Date. Try “now”, or “next Wednesday”, or “ 2 weeks 4 days 23 hours 9 seconds”.
  • Extended to handle Months and Years in the past (JavaScript version only goes to weeks)

Usage:

// pass in a String DateTime, compared to another String DateTime (defaults to now)
$myString = Date_Difference::getStringResolved('-7 weeks');
$myString = Date_Difference::getStringResolved('-7 weeks', '+1 week');
 
// pass in a DateTime object, compared to another DateTime object (defaults to now)
// useful with the Propel ORM, which uses DateTime objects internally.
$myString = Date_Difference::getString(new DateTime('-7 weeks'));
$myString = Date_Difference::getString(new DateTime('-7 weeks'), new DateTime('+1 week'));

Thanks for the script!

Using in a new wordpress plugin, props dude, seems to fail for sub hours though...

Looking back on this script, I don't know that I'd recommend using it.

It makes more sense to output UTC and then pretty it up using JavaScript instead. Then you can cache your HTML. See this implementation. Also on GitHub.
