There is a broken link on http://docs.mongodb.org/ecosystem/drivers/php/

where it says:

If you are using Eclipse, you can get Content Assist working by downloading the mongo_version.zip package.

This hyperlink is broken and leads to an invalid project.

Should fix the link to point to the new location of the project (if it still exists) as the Content Assist package is very useful for Eclipse users developing with the PHP driver.
