Über Laravel-Spickzettel

Dieser Laravel-Spickzettel verdichtet die Framework-Oberfläche, mit der Sie täglich arbeiten: Artisan-CLI, Routing, Controller, Eloquent-ORM, den Query Builder, Migrationen und Schema, Blade-Templates, Validierung, Requests und Responses, Collections, Auth und Middleware sowie Hilfsfunktionen.

Laravel hat eine ausdrucksstarke, aber breite API — die exakte Eloquent-Beziehungssignatur, ein Migrations-Spaltenmodifikator, ein Validierungsregelname, eine Collection-Methode —, und jede Zeile hier zeigt den echten Aufruf mit einer knappen Beschreibung, sodass sich der Spickzettel wie das Framework in Kurzform liest.

Er ist kostenlos und läuft vollständig im Browser. Filtern Sie jedes Snippet live mit dem Suchfeld, springen Sie über das fixierte Inhaltsverzeichnis zwischen Abschnitten, kopieren Sie Code mit einem Klick und drucken Sie den Spickzettel für eine Framework-Referenz beim Programmieren aus.

So verwenden Sie Laravel-Spickzettel

Überfliegen Sie die zwölf Abschnitte, von Artisan-CLI und Routing über Eloquent-ORM bis Hilfsfunktionen & Sonstiges.
Suchen Sie nach einem Begriff wie migration, hasMany oder validate, um den Spickzettel live zu filtern.
