PHPDocs are unavailable when hovering over a function which is defined in an external directory.
They are available when using code suggestion.
Steps to reproduce:
- Create a PHP project
- Create a PHP file outside the workspace containing a function with documentation
- Add the directory containing the PHP file to the PHP buildpath: 'Project -> Properties -> PHP Buildpath -> External Directories'
- In a PHP file in the project, begin typing the name of the function. PHPDocs are available in the suggestion popup
- Once the name of the function is written down, hovering over it shows "No available documentation"
Hovering should show the documentation.
