I take it you are on Windows. In windows I usually use phpDesigner (http://www.mpsoftware.dk/phpdesigner.php) which has pretty good CC. In linux, I use geany(http://www.geany.org/) or vim both of which have CC, in the later case, you will need to set it up. I found Eclipse to be too bloated and I got sick of waiting for it to startup. :\
