How to make your editor add empty line at the end of file

PHP recommends adding empty line at the end of php files. But now other people find it great, especailly when comparing difference in github.

To make your editor add empty line in the end of file:

Ensure your IDE/editor has the relevant setting set:

• IntelliJ: navigate to Settings > Editor > General and
  • check Ensure line feed at file end on Save
  • set Strip trailing spaces on Save to Modified Lines
• VSC: navigate to Preferences > Settings and
  • search for “newline” and check the following
    • Files: Insert Final Newline
    • Files: Trim Final Newlines
  • search for “whitespace” and check Trim Trailing Whitespace
• Sublime Text: navigate to Preferences > Settings > Default find and set the following to true:
  • trim_trailing_white_space_on_save
  • ensure_newline_at_eof_on_save
  • … or use Single Trailing Newline package to ensure one and only one newline at the end of file

Other IDEs may have a setting similar to any of the above.
