Laravel 5 Collections: Creating a Copy of a Collection With toBase

The toBase method will return a new collection instance containing all of the data in the current collection instance. This can be useful for method chaining when you need to modify the collection's contents without changing the original collection instance.

#Signature

1public function toBase();

#Example Use

 6    'Charlie',
 7]);
 8 
 9// Create an uppercase-variant collection of names.
10$upperCaseNames = $names->toBase()->map(function ($name) {
11   return mb_strtoupper($name);
12});

After the above code has executed, the local variables would contain the following elements:
