WireArray::findRandomTimed() method

Find a quantity of random elements from this WireArray based on a timed interval (or user provided seed).

If no $seed is provided, today's date (day) is used to seed the random number generator, so you can use this function to rotate items on a daily basis.

Idea and implementation provided by mindplay.dk


// Get same 3 random items per day
$randomItems = $items->findRandomTimed(3);

// Get same 3 random items per hour
$randomItems = $items->findRandomTimed('YmdH'); 


// basic usage
$items = $wireArray->findRandomTimed(int $num);

// usage with all arguments
$items = $wireArray->findRandomTimed(int $num, $seed = 'Ymd');



The amount of items to extract from the given list

seed (optional)int, string

Optionally provide one of the following:

  • A PHP date() format string.
  • A number used to see the random number generator.
  • The default is the PHP date format "Ymd" which makes it randomize once daily.

Return value

“We were really happy to build our new portfolio website on ProcessWire! We wanted something that gave us plenty of control on the back-end, without any bloat on the front end - just a nice, easy to access API for all our content that left us free to design and build however we liked.” —Castus, web design agency in Sheffield, UK
