This may not be the speediest way to get the first or last element from an array but it's probably simplest (and most obvious) to be able to just type `array_first($arr)` and `array_last($arr)`(in particular for associative arrays). Therefore in most cases this would do the job and fits the purpose of these methods.\r\n\r\nAdditionally other methods of grabbing the first item in an associative array, such as using `reset()`, require a variable to be passed by reference. This means we can't do something like `$first = reset(config('some.item'));` but `$first = array_first(config('some.item'));` works fine.\r\n\r\nThanks for your consideration.","created_at":"2016-02-28T03:21:28Z","updated_at":"2016-02-28T21:32:05Z","closed_at":null,"merged_at":null,"merge_commit_sha":"7e0c0fa5a3f4e6d3a78160457c02324b407667a9","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/laravel/framework/pulls/12527/commits","review_comments_url":"https://api.github.com/repos/laravel/framework/pulls/12527/comments","review_comment_url":"https://api.github.com/repos/laravel/framework/pulls/comments{/number}","comments_url":"https://api.github.com/repos/laravel/framework/issues/12527/comments","statuses_url":"https://api.github.com/repos/laravel/framework/statuses/b7df7cb8b56075f281ff8a37988ea59c5a913b21","head":{"label":"mhayes14:5.2","ref":"5.2","sha":"b7df7cb8b56075f281ff8a37988ea59c5a913b21","user":{"login":"mhayes14","id":591318,"avatar_url":"https://avatars.githubusercontent.com/u/591318?v=3","gravatar_id":"","url":"https://api.github.com/users/mhayes14","html_url":"https://github.com/mhayes14","followers_url":"https://api.github.com/users/mhayes14/followers","following_url":"https://api.github.com/users/mhayes14/following{/other_user}","gists_url":"https://api.github.com/users/mhayes14/gists{/gist_id}","starred_url":"https://api.github.com/users/mhayes14/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mhayes14/subscriptions","organizations_url":"https://api.github.com/users/mhayes14/orgs","repos_url":"https://api.github.com/users/mhayes14/repos","events_url":"https://api.github.com/users/mhayes14/events{/privacy}","received_events_url":"https://api.github.com/users/mhayes14/received_events","type":"User","site_admin":false},"repo":{"id":52701705,"name":"framework","full_name":"mhayes14/framework","owner":{"login":"mhayes14","id":591318,"avatar_url":"https://avatars.githubusercontent.com/u/591318?v=3","gravatar_id":"","url":"https://api.github.com/users/mhayes14","html_url":"https://github.com/mhayes14","followers_url":"https://api.github.com/users/mhayes14/followers","following_url":"https://api.github.com/users/mhayes14/following{/other_user}","gists_url":"https://api.github.com/users/mhayes14/gists{/gist_id}","starred_url":"https://api.github.com/users/mhayes14/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mhayes14/subscriptions","organizations_url":"https://api.github.com/users/mhayes14/orgs","repos_url":"https://api.github.com/users/mhayes14/repos","events_url":"https://api.github.com/users/mhayes14/events{/privacy}","received_events_url":"https://api.github.com/users/mhayes14/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/mhayes14/framework","description":"","fork":true,"url":"https://api.github.com/repos/mhayes14/framework","forks_url":"https://api.github.com/repos/mhayes14/framework/forks","keys_url":"https://api.github.com/repos/mhayes14/framework/keys{/key_id}","collaborators_url":"https://api.github.com/repos/mhayes14/framework/collaborators{/collaborator}","teams_url":"https://api.github.com/repos/mhayes14/framework/teams","hooks_url":"https://api.github.com/repos/mhayes14/framework/hooks","issue_events_url":"https://api.github.com/repos/mhayes14/framework/issues/events{/number}","events_url":"https://api.github.com/repos/mhayes14/framework/events","assignees_url":"https://api.github.com/repos/mhayes14/framework/assignees{/user}","branches_url":"https://api.github.com/repos/mhayes14/framework/branches{/branch}","tags_url":"https://api.github.com/repos/mhayes14/framework/tags","blobs_url":"https://api.github.com/repos/mhayes14/framework/git/blobs{/sha}","git_tags_url":"https://api.github.com/repos/mhayes14/framework/git/tags{/sha}","git_refs_url":"https://api.github.com/repos/mhayes14/framework/git/refs{/sha}","trees_url":"https://api.github.com/repos/mhayes14/framework/git/trees{/sha}","statuses_url":"https://api.github.com/repos/mhayes14/framework/statuses/{sha}","languages_url":"https://api.github.com/repos/mhayes14/framework/languages","stargazers_url":"https://api.github.com/repos/mhayes14/framework/stargazers","contributors_url":"https://api.github.com/repos/mhayes14/framework/contributors","subscribers_url":"https://api.github.com/repos/mhayes14/framework/subscribers","subscription_url":"https://api.github.com/repos/mhayes14/framework/subscription","commits_url":"https://api.github.com/repos/mhayes14/framework/commits{/sha}","git_commits_url":"https://api.github.com/repos/mhayes14/framework/git/commits{/sha}","comments_url":"https://api.github.com/repos/mhayes14/framework/comments{/number}","issue_comment_url":"https://api.github.com/repos/mhayes14/framework/issues/comments{/number}","contents_url":"https://api.github.com/repos/mhayes14/framework/contents/{+path}","compare_url":"https://api.github.com/repos/mhayes14/framework/compare/{base}...{head}","merges_url":"https://api.github.com/repos/mhayes14/framework/merges","archive_url":"https://api.github.com/repos/mhayes14/framework/{archive_format}{/ref}","dow
