關於 Laravel 速查表

這份 Laravel 速查表濃縮了你每天會接觸到的框架內容:Artisan 指令列、路由、控制器、Eloquent ORM、查詢建構器、資料庫遷移與結構、Blade 樣板、驗證、請求與回應、集合(Collections)、驗證與中介層,以及輔助函式。

Laravel 的 API 表達力強但範圍廣——確切的 Eloquent 關聯寫法、遷移欄位修飾詞、驗證規則名稱、集合方法等等,每一列都附上實際的呼叫方式與一行說明,讓這份速查表讀起來就像框架的速記版。

完全免費,且完全在瀏覽器端呈現。用搜尋框即時篩選每個程式碼片段,透過置頂目錄在各區段間跳轉,一鍵複製程式碼,還能列印下來當作建置時的框架參考。

如何使用 Laravel 速查表

瀏覽十二個區段,從「Artisan 指令列」「路由」一路到「Eloquent ORM」與「輔助工具與其他」。
搜尋像 migration、hasMany 或 validate 這類詞彙,即時篩選速查表。
透過置頂側邊欄跳轉到「Blade 樣板」或「集合」等區段。
點擊程式碼片段或其複製圖示,即可將 PHP 程式碼複製到你的專案中。
列印這份速查表,作為離線的 Laravel 參考。

常見問題

共十二個區段:Artisan 指令、路由、控制器、Eloquent、查詢建構器、資料庫遷移與結構、Blade、驗證、請求與回應、集合、驗證與中介層,以及一般輔助函式。

有。Artisan 區段列出你經常執行的產生器、遷移、快取與維護指令,每一項都附上簡短說明,說明它會產生或執行什麼。

有。Eloquent 區段展示模型定義、關聯與查詢寫法,另外還有獨立的查詢建構器區段,涵蓋你需要時可用的底層流暢式 API。

可以。點擊任何一列的程式碼或滑鼠懸停時出現的複製圖示,就會立即複製到剪貼簿。

是的,免費、可搜尋、可列印,無需帳號即可使用。
