How to use PsySH with a Yii2 application

Using PsySH (GitHub) as the Yii2 shell

  • Issue the following commands from the command line in your Yii application directory:
    • chmod +x psyii
    • mkdir extensions/yiishell
    • wget -O extensions/yiishell/psysh psysh.org/psysh
    • chmod +x extensions/yiishell/psysh
  • Copy the file init.php below to psysh/init.php and update any paths to work with your application configuration
  • Copy the file config.php below to psysh/config.php. Change or add to the config array with the options you'd like to use (available options)
  • Now you can start PsySH with the command ./psyii psysh/init.php --config psysh/config.php
