URL Formats Routing Creating URLs Using Pretty URLs Performance Consideration When a Yii application starts processing a requested URL, the first step it takes is to parse the URL into a route. The route is then used to instantiate the corresponding controller action to handle the request. This whole process is called routing. The reverse process of routing is called URL creation, which creates a URL from a given route and the associated query parameters. When the created URL is later requeste

In particular, after taking over the control from applications, controllers will analyze incoming request data, pass them to models, inject model results into views, and finally generate outgoing responses. Actions Controllers a

For Web applications, this is of particular importance because the potential users may be worldwide. Yii offers a full spectrum of I18N features that support message translation, view tra

Building Queries Query Methods Built on top of Database Access Objects, query builder allows you to construct a SQL query in a programmatic and DBMS-agnostic way. Compared to writing raw SQL statements, using query builder will help you write more readable SQL-related code and generate more secure SQL statements. Using query builder usually involves two steps: Build a yii\db\Query object to represent different parts (e.g. SELECT, FROM) of a SELECT SQL statement. Execute a query method (e.g. a
