Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. It is written primarily in Java to provide software developers and administrators an integrated development environment (IDE). De PDT version for PHP can be downloaded from Zend.
In its default form it is meant for Java developers, consisting of the Java Development Tools (JDT). Users can extend its capabilities by installing plugins written for the Eclipse software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules. Language packs provide translations into over a dozen natural languages.
