PhpStorm can navigate to functions and classes out of the box but there is added support for Joomla specific cases. The Joomla specific cases it can understand are:
- Language strings
In Joomla multi-lingual support is enabled through the JText function. A common way to enter a language string is like this:
This will translate to "No Matching Results" but to find in which language file this string is to be found is usually quite a search. PhpStorm makes it easy that you can navigate to the language file by hitting CTRL-B / CMD-B. If the language string is present in more than one file, a popup is shown with the possible options.
echo HTMLHelper:_('searchtools.sort', 'JSTATUS', 'a.state', $listDirn, $listOrder
To find where the sort function is located is quite the challenge because you first need to go to HTMLHelper and follow the code from there. PhpStorm makes life a lot easier by jumping straight to the sort function if you hit CTRL-B / CMD-B on the searchtools.sort.
Not only can you jump to the function declaration, PhpStorm will also show you the documentation for the function by hitting CTRL-Q / F1. This will help in understanding the parameters required and/or available for that specific function.
