Download TruStudio from
http://www.xored.com/trustudio/
There are two versions. TruStudio Foundation and TruStudio Professional.
However Foundation is free to use.
(trustudio-foundation-1.0-win32.zip)
Unzip the file and overwrite to C:\eclipse
PHP modules
To use extension modules as mbstring and oracle (oci8), you need to manually
install the modules.
Download the same version of PHP as TruStudio uses. i.e. php-5.0.2-Win32.zip
Unzip the downloaded file, and copy modules (dlls) to
C:\eclipse\plugins\org.trustudio.php.binaries.sapi.win32_5.0.2\os\win32\x86\cgi
. I copied php_mbstring.dll and php_oci8.dll for example.
