If you’re in a PHP file, the Emmet shortcuts don’t initially work.
To make them work, however, we just need to edit an Atom configuration file.
- Open the command palette: command-shift-p.
- Type in the following to search for the file: keymap.cson
- Press Return when that result shows up.
- After the commented out section, paste the following:
'atom-text-editor[data-grammar="text html php"]':
'tab': 'emmet:expand-abbreviation-with-tab'
In a PHP file, test an Emmet shortcut. If it doesn’t work, restart Atom and try again.
