last($array, callable $callback = null, $default = null)

The last helper method is the logical opposite of the first (discussed in the article Laravel Array Helper Function: array_first method. The difference is that the last function will return the last value to satisfy the $callback function. If no value is returned from the $callback function, the $default value is returned.

Using the same $isPostFormat function from the array_first article:

1<?php
2 
3use Illuminate\Support\Str;
4 
5$isPostFormat = function($key, $value) {
6    return Str::is('/post/*', $value);
7};

we could get the last post in the following array like so:

 1<?php
 2 
 3use Illuminate\Support\Arr;
 4 
 5$postsArray = [
 6    '/post/first-post',
 7    '/post/second-post',
 8    '/post/last-post'
 9];
10 
11$lastPost = Arr::last($postsArray, $isPostFormat);

the value of $lastPost would be:

/post/last-post

#Optional $callback Parameter

The $callback function is an optional parameter, and can be omitted. When the $callback parameter is omitted, the last method will return the last item in the array:

1<?php
2 
3use Illuminate\Support\Arr;
4 
5// 'something else'
6$firstItem = Arr::last($sampleArray);

#array_last($array, $callback, $default = null)

The array_last function is a shortcut to calling Arr::last. This function is declared in the global namespace.
