why do you want to move away from C++?...basics to basic. and SQL, PHP, EXCEL and all those are for business/web/networking(there are many more but my knowledge of that side ofthings is bare minimum)..so if your going in that direction of a carerr go for it...
If you want to stick to science/gaming/math/robotics/3D-VR/ALIFE/AI
stick to C/C++ learn C for its fundamental functions.then move to the convetions of C++ or learn to intertwine conventions like i do.(NOT PURE OO for me,i can't stand it)
if your in high school- learn to use C/C++ packages the Direct series by MS, or the open series(opengl,openAL,openAI, openDynamics) then learn to use some numerical pkgs and 3D engines(torqu,eunreal, hl, ogre)...
