Available Methods
For the remainder of this documentation, we’ll discuss each method available on the Collection
class. Remember, all of these methods may be chained for fluently manipulating the underlying
array. Furthermore, almost every method returns a new Collection instance, allowing you to
preserve the original copy of the collection when necessary.
You may select any method from this table to see an example of its usage:
A> #collection-method-list > p { A> column-count: 3; -moz-column-count: 3; -webkitcolumn-count:
3; A> column-gap: 2em; -moz-column-gap: 2em; -webkit-column-gap: 2em; A> } A>
A> #collection-method-list a { A> display: block; A> }

Method Listing
A> #collection-method code { A> font-size: 14px; A> } A> A> #collection-method:not(.firstcollection-method)
{ A> margin-top: 50px; A> }
all() {#collection-method .first-collection-method}
The all method simply returns the underlying array represented by the collection:
1 collect([1, 2, 3])->all();
2
3 // [1, 2, 3]
avg() {#collection-method}
The avg method returns the average of all items in the collection:
