如何将 Eclipse 用于 Java 和 PHP?

There are Eclipse IDE for Java EE Developers (190 MB) and Eclipse for PHP Developers (139 MB)

I've already installed Eclipse for PHP.

I don't want to install another eclipse for Java.

Is it possible to use the same Eclipse for both Java and PHP?

EDIT

I decide to install another Eclipse for Java finally....

• Select Help -> Install new Software
• Select http://download.eclipse.org/technology/epp/packages/galileo as update site URL (or add it if it's missing)
• Select "EPP Java Package" and (if you want to write web apps) "Java EE IDE Feature" to install
