Since 6.0.0, PHP Development Tools use common Project Explorer.
The Project Explorer view is an internal file system browser, allowing you to view all PHP projects and files in your Workspace. It shows the PHP element hierarchy of PHP projects in the Workbench and provides you with a PHP-specific view of your available resources. Within each project, source folders and referenced libraries are shown in the tree. In addition, this view shows all PHP code elements (classes, functions, variables, etc.). Clicking an element or declaration will cause the corresponding code to be displayed in the PHP editor.
See PHP Icons for a description of the icons displayed in the Project Explorer view.
| Icon | Name | Description |
|---|---|---|
 | Back/Forward | Scrolls backwards and forwards through your recently navigated resources. These icons will only be active if the 'Go into the selected element' option is selected in the PHP Preferences Page (available from Window | Preferences | PHP). |
 | Up | Navigates up one level. This icon will only be active if the 'Go into the selected element' option is selected in the PHP Preferences Page (available from Window | Preferences | PHP). |
 | Collapse All | Collapses the list of elements |
 | Link with Editor | If selected, elements will immediately be displayed in the editor when selected. If unselected, elements will be displayed in the editor when they are double-clicked. |
The view's menu can be accessed through the view menu icon
