General purpose helper methods

Array Helpers

• Arr::toAssoc - convert a random array to a strict structure - every entry has a string key
• Arr::invoke - if the array holds only objects, aggregate the results of a method call on all the objects
• Arr::pluckProperty - aggregate the value of a property of each object in the array
• Arr::pluckUniqueProperty - aggregate the value of a property of each object in the array, only unique values
• Arr::pluck - aggregate all the values of entries with a given key
• Arr::flatten - flatten all the values of nested arrays
• Arr::groupBy - group by result of callback

SplObjectStorage Helpers

• Objects::invoke - aggregate the results of a method call on all the objects
• Objects::filter - similar to array_filter, but for SplObjectStorage
• Objects::toArray - convert SplObjectStorage into an array
• Objects::fromArray - convert an array into a SplObjectStorage
• Objects::sort - sort a SplObjectStorage using a comparation closure
• Objects::groupBy - change SplObjectStorage where the "key" object is the result of a callback, and all the other objects are grouped by them
