I just figured out that all code completion for Eclipse is stored in plain files located here (example):
.\eclipse\plugins\org.eclipse.php.core_2.1.1.v20090921-1100\Resources\language
I tried adding global variables like $_POST, $_GET, $_SERVER
to the end of basic.php
but without any luck (did try to restart Eclipse).
Is there a way to create compatible files for the needs of "smooth integration" of (ie.)CodeIgniter framework by adding or changing files located here and how would it be done?
