so, which is that? i saw many things that are almost the same with php... i guess the reason is that php is kinda webc++..

thanx in advance.

Two big differences come to mind right away:
1. compilation -- C++ code needs to be compiled into a .exe, PHP is interpreted directly from the source by Apache.
2. types -- C++ is strongly typed, PHP has no variable types (well, there are types, but a variable can change types throughout the program). Functions don't need specific return types, parameters don't need types either.

Variables in PHP have to start with $. There are some differences associated with classes and especially polymorphism and inheritance.

But you are right; the syntax and concepts are very similar. PHP is much more forgiving than C++ in some ways (with variable types and such).
