How do I pass parameters to a route in Yii?
There are three steps for passing parameters to route in Yii: first, use the createUrl method to generate a URL with parameters, second, enable a beautiful URL by configuring the urlManager and set custom rules, and finally, automatically bind the parameters in the controller through $request->get() or method parameters. Specifically: 1. When generating the URL, the parameters are appended in an array to the path; 2. Enable enablePrettyUrl and definition rules in the configuration file to achieve a more readable URL; 3. Directly obtain the parameter name in the controller or use the get method and provide default value processing. At the same time, pay attention to distinguishing the different sources and usage scenarios of query parameters and routing parameters.

How to eager load relationships in Laravel
To resolve N 1 query issues in Laravel, you must use eagerloading. 1. Use the with() method to preload relationships during query, such as User::with('posts')->get() can optimize the query into two; 2. Support nested loading through point syntax, such as with('posts.comments.author') to achieve multi-layer relationship preloading; 3. You can load conditions through closure constraints, such as loading only published articles; 4. Use the load() method to achieve delayed preloading, which is suitable for scenarios where relationships need to be loaded after subsequent condition judgments; 5. Avoid N 1 problems caused by accessing relationships in a loop, and with() should be with() in advance
