CodeIgniter 4 provides built-in command spark and useful commands and library. You can also create spark commands, and run controllers via CLI.
What is the CLI?
The command-line interface is a text-based method of interacting with computers. For more information, check the Wikipedia article.
Why Run via the Command-Line?
There are many reasons for running CodeIgniter from the command-line, but they are not always obvious.
Run your cron-jobs without needing to use wget or curl.
Make interactive “tasks” that can do things like set permissions, prune cache folders, run backups, etc.
Integrate with other applications in other languages. For example, a random C++ script could call one command and run code in your models!
The Spark Commands
CodeIgniter ships with the official command spark and built-in commands.
You can run the spark and see the help:
> php spark
See the Spark Commands page for detailed information.
The CLI Library
The CLI library makes working with the CLI interface simple. It provides easy ways to output text in multiple colors to the terminal window. It also allows you to prompt a user for information, making it easy to build flexible, smart tools.
See the CLI Library page for detailed information.
