Quick Documentation Lookup helps you get quick information for any symbol or just method signature information, provided that this symbol has been supplied with documentation comments in the applicable format.
- For markup languages, PhpStorm retrieves reference from the language specification according to the Document Type setting.
- Documentation look-up is also available for Drupal hooks, see Drupal.
Documentation is shown in the Documentation pop-up window:
The URLs and e-mail addresses specified in the documentation comments for methods are also properly rendered. Clicking a hyperlink opens the corresponding URL in an external browser; clicking an e-mail address opens the default mail client.
