Finding All Permutations of an Array (PHP Cookbook)David SklarAdam Trachtenberg
And of course, an extension method to make this available to any enumeration: /// /// Retrieves all possible permutations of a set of items. /// /// <typeparam name="T">The type of the items in the original set.</typeparam> /// The original set of items over ...
The crossJoin method cross joins the collection with the given array or collection, returning all possible permutations:const collection = collect([1, 2]); const joined = collection.crossJoin(['a', 'b']); joined.all(); // [ // [1, 'a'], // [1, 'b'], // [2, 'a'], //...
