To install the Yii framework, you need to configure PHP and Composer according to different operating systems. The specific steps are as follows: 1. You need to manually download PHP and configure environment variables on Windows, then install Composer, use commands to create a project and run a built-in server; 2. It is recommended to use Homebrew to install PHP and Composer, then create a project and start a development server; 3. Linux (such as Ubuntu) install PHP, extensions and Composer through apt, then create a project and deploy a formal environment with Apache or Nginx. The main differences between different systems are in the environment construction stage. Once PHP and Composer are ready, the subsequent processes are consistent. Note

It is crucial to clearly display verification errors when the user submits the form information incorrectly or missing. 1. Use inline error messages to directly display specific errors next to the relevant fields, such as "Please enter a valid email address", rather than general prompts; 2. Mark the problem fields visually by red borders, background colors or warning icons to enhance readability; 3. When the form is long or the structure is complex, display a click-through summary of the error that can be clicked and jumped at the top, but it needs to be used in conjunction with inline messages; 4. Enable real-time verification in the appropriate situation, and instant feedback when the user enters or leaves the field, such as checking the email format or password strength, but avoiding prompting too early before the user submits. These methods can effectively guide users to quickly correct input errors and improve the form filling experience.
