== 功能 ==
以下幾點為 Laravel 的核心設計理念<ref>其餘未具體指出的，可以參考 Laravel 3 技術文件的功能敘述:{{Cite web|url=http://code.tutsplus.com/tutorials/why-laravel-is-taking-the-php-community-by-storm--pre-52639|title=Why Laravel is Taking the PHP Community by Storm|accessdate=2015-05-09|author=Jeffrey Way|date=2012-11-28|archive-date=2015-05-05|archive-url=https://web.archive.org/web/20150505001943/http://code.tutsplus.com/tutorials/why-laravel-is-taking-the-php-community-by-storm--pre-52639|dead-url=no}}</ref>
*'''Eloquent ORM''' ([[对象关系映射|物件關係對映]])：將 [[Active Record|Active Record 模式]] 以 PHP 實作，提供一些函式來建立 [[資料庫]] 物件之間的關聯。 依照 Active Record 模式的原則，Eloquent ORM 以 [[类 (计算机科学)|類別]] 代表 [[資料表]]，並將這些類別的物件實例與資料表中的單一筆資料做綁定。<ref>{{Cite web|url=http://www.enukesoftware.com/blog/eloquent-orm-in-laravel-what-and-why|title=Eloquent ORM in Laravel: What and Why!|accessdate=2014-12-19|archive-url=https://web.archive.org/web/20141219144311/http://www.enukesoftware.com/blog/eloquent-orm-in-laravel-what-and-why/|archive-date=2014-12-19|dead-url=yes}}</ref><ref>{{Cite web|url=http://www.developer.com/lang/php/develop-faster-with-the-laravel-php-framework.html|title=Develop Faster with the Laravel PHP Framework|accessdate=2015-04-17|archive-date=2020-12-03|archive-url=https://web.archive.org/web/20201203172615/https://www.developer.com/lang/php/develop-faster-with-the-laravel-php-framework.html|dead-url=no}}</ref>
* '''Query builder'''：於 Laravel 3 釋出，提供一個能更直接的存取 Eloquent ORM 的管道。 與其撰寫 [[查询 (SQL)|SQL 查詢語法]]，Laravel 的 query builder 提供了一系列的類別與 [[方法 (電腦科學)|函式]]，得以使用程式化呼叫的方式來執行 SQL 查詢。 同時也可以對查詢語法的執行結果做（可再被查詢的）快取。<ref>{{Cite web|url=http://laravel.com/docs/4.0/queries|title=Laravel documentation (version 4.0): Query builder|accessdate=2015-04-27|archive-url=https://web.archive.org/web/20150324070108/http://laravel.com/docs/4.0/queries|archive-date=2015-03-24|dead-url=yes}}</ref>
* '''Application logic'''：在專案中將其他已開發的功能整合，顯著的案例為 Controller 的使用與路由的宣告。 其語法與 Sinatra 框架相似。
* '''Reverse routing'''：為專案內的超連結建立成一個一個的路由，當套用了路由的超連結被修改，便會自動更新所有使用了該路由的超連結。 使用時需要填入要使用的路由的名稱，Laravel 會將他們轉換成對應的 [[统一资源标志符|URIs]]。
* '''Restful controllers'''：提供一種將 [[超文本传输协议|HTTP GET]] 和 POST requests 背後的邏輯切割的方式。
* '''Class auto loading'''：自動載入 PHP 的類別，不須手動維護所有類別的引用路徑。類別只會在被使用到的當下才載入，避免載入不須要的類別。
* '''[[MVC|View]] composers'''：是可自定義的一些程式碼區塊，當 view 被載入時便會被執行。
<!---
* ''Blade'' templating engine combines one or more templates with a [[数据模型|data model]] to produce resulting views, doing that by [[源代码至源代码编译器|transpiling]] the templates into cached PHP code for improved performance.  Blade also provides a set of its own [[控制流程|control structures]] such as [[條件運算式|conditional statements]] and loops, which are internally mapped to their PHP counterparts.  Furthermore, Laravel services may be called from Blade templates, and the templating engine itself can be extended with custom directives.<ref>{{Cite web|url=http://laravel.com/docs/5.1/blade|title=Laravel documentation (version 5.1): Blade Templates|accessdate=2015-06-10|author=Dayle Rees|year=2014}}</ref><ref>{{Cite web|url=http://daylerees.com/codebright/blade|title=Laravel Blade engine|accessdate=2015-06-10|author=Dayle Rees|year=2014}}</ref>
* ''IoC containers'' make it possible for new objects to be generated by following the [[控制反转|inversion of control]] (IoC) principle, in which the framework calls into the application- or task-specific code, with optional instantiating and referencing of new objects as [[单例模式|singletons]].
* ''Migrations'' provide a [[版本控制|version control]] system for database schemas, making it possible to associate changes in the application's codebase and required changes in the database layout.  As a result, this feature simplifies the [[软件部署|deployment]] and updating of Laravel-based applications.<ref name="docs-migrations">{{Cite web|url=http://laravel.com/docs/5.0/migrations|title=Laravel documentation (version 5.0): Migrations and seeding|accessdate={{date|2015-04-27|mdy}}}}</ref>
* ''Automatic pagination'' simplifies the task of implementing pagination, replacing the usual manual implementation approaches with automated methods integrated into Laravel.
* ''Form request'' is a feature of Laravel 5 that serves as the base for [[Web Forms|form]] input validation by internally binding event listeners, resulting in automated invoking of the form validation methods and generation of the actual form.<ref>{{Cite web|url=https://www.tisindia.com/blog/laravel-best-php-framework-2015/|title=Creating a Contact Form in Laravel 5 Using the Form Request Feature!|accessdate={{date|2015-03-02|mdy}}|author=Manmeet Anand}}</ref>

* '''Database seeding'''：提供一種管道來把預設的資料用來填充到資料庫，便於進行[[软件测试]]，或被作為應用程式最初的建置步驟。<ref>{{cite web |url= https://aquatecinnovative.com/laravel-development-services/ |title= Laravel Development Services |author= Sahil Sharma |publisher= Aquatec Innovative Private Limited |access-date= 2022-09-09 |archive-date= 2022-12-06 |archive-url= https://web.archive.org/web/20221206173609/https://aquatecinnovative.com/laravel-development-services/ |dead-url= no }}</ref> 
* '''Filesystem'''：於 Laravel 5.0 新增，統一了 [[文件系统|檔案系統]] 的函式，讓本地端和 [[雲端運算|雲端]] 儲存空間（如 [[Amazon S3|亞馬遜 S3]]、[[Rackspace Cloud]]）的操作邏輯一致。<ref>{{cite web |url=https://laravel.com/docs/master/filesystem |title=File Storage - Laravel - The PHP Framework For Web Artisans |publisher=laravel.com |accessdate=February 28, 2020 |archive-date=2020-11-29 |archive-url=https://web.archive.org/web/20201129005830/https://laravel.com/docs/master/filesystem |dead-url=no }}</ref>
* '''[[单元测试]]''' 也被整合到了 Laravel，其包括的測試案例能夠偵測並預防框架內的[[迴歸]]，並可以使用 Artisan CLI 來執行單元測試.
* '''Homestead'''： 一個[[Vagrant]][[虛擬機器|虛擬機]]，預載了 Laravel 開發者需要的所有開發工具，包括 [[Ubuntu]]，Gulp，Bower 以及其他輔助網頁開發的工具。<ref>{{Anchor|CASHIER|FLYSYSTEM|SOCIALITE}}</ref>
* '''Lazy Collection'''：於 Laravel 6 新增，使用 [[PHP]] 的 generators 來處理大量資料，同時保持較低的內存使用率。<ref>{{Cite web|url=https://laravel.com/docs/6.x/collections#lazy-collections|title=Collections - Laravel - The PHP Framework For Web Artisans|access-date=28 February 2020|archive-date=2020-11-12|archive-url=https://web.archive.org/web/20201112025518/https://laravel.com/docs/6.x/collections#lazy-collections|dead-url=no}}</ref>

=== Artisan CLI ===
Laravel 的 [[命令行界面|命令列介面]] (CLI)，稱為 ''Artisan''，於 Laravel 3 推出時功能還相當有限。 隨後 Laravel 將架構改為以 [[Composer]] 作為基底，讓 Artisan 得以和 [[Symfony]] 框架的元件互補，也因此 Laravel 4 的 Artisan 提供了更多的功能。<ref>{{Cite web | url = http://code.tutsplus.com/tutorials/your-one-stop-guide-to-laravel-commands--net-30349 | title = Your One-Stop Guide to Laravel Commands | date = 2013-02-28 | accessdate = 2015-05-09 | author = Jason Lewis | website = code.tutsplus.com | archive-date = 2015-05-18 | archive-url = https://web.archive.org/web/20150518024938/http://code.tutsplus.com/tutorials/your-one-stop-guide-to-laravel-commands--net-30349 | dead-url = no }}</ref>

Artisan 的功能被分散到不同的子命令，用以協助打造與管理這些由 Laravel 建構而成的軟體。最常見的使用情境如：操作資料庫的 migration & seeding、汲取套件的靜態資源、為新建立的 controller 或 migration 產生程式碼樣板（為開發者省去重複撰寫相同程式碼的時間）。開發者也可以自行新增新的命令，來擴充 Artisan 的功能（如自動化的執行任務）。<ref name="packt-getting-started" />
