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

Example

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

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

Usage

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

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

“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
