Configuring the Server

Since TYPO3 is written in the PHP scrpting language, you will need a webserver like Apache with PHP (version 5.2 or 5.3) support, for your TYPO3 development. Additionally TYPO3 requires a MySQL database for data storage. If you don’t have a local development server yet, we recommend the XAMPP package (http://www.apachefriends.org/xampp.html). It will install Apache, PHP, MySQL and other useful tools on all established operating systems (Linux, Windows, Mac OS X). Now you can install TYPO3 on your test system.

For production systems you are advised to use a PHP Opcode Cache like eAccelerator (http://eaccelerator.net), as it caches the compiled PHP code often reducing script loading times by more than half. By default eAccelerator will not cache PHP comments. However, as Extbase uses these comments to retrieve important information, eAccelerator must not omit them. To achieve this you need to configure eAccelerator with the option --with-eaccelerator-doc-comment-inclusion. A complete installation of eAccelerator will then work as follows: First download the eAccelerator source code and navigate to the source directory using the console. You have to adjust the eAccelerator source to your installed PHP version by running the command phpize. After this you can configure the eAccelerator source code not to remove the PHP comments by running ./configure --with-eaccelerator-doc-comment-inclusion. Now compile eAccelerator with the command make. To finish the installation run make install as the root user.

It might be neccessary to adjust your PHP configuration to load eAccelerator. Now you can check if your source code comments are preserved by using a TYPO3 instance. Install the extbase Extension in the TYPO3 backend by using the Extension Manager and then open the Reports module. Select the Status Report submodule and have a look at the extbase section, which will tell you whether the PHP comments are preserved or not.
