Enter Debug Mode

If you need to enter debug mode, such as viewing DB Queries, complete error messages, or want to prevent CSS/JS caching, you can enter debug mode.

The simplest way is to add /dev.php at the end of the website URL.

For example:

In this case, we are using PHP server: http://localhost:8000, we can simply add dev.php after ths host: http://localhost:8000/dev.php

This will enter debug mode.

When an error occurs, it can also display complete error messages.

Force Debug Mode

Add APP_DEBUG=1 to .env file to force enable debug mode without accessing dev.php.
