Call a command-line C++ compiler using system, exec, or backticks. There is no C++ compiler written in PHP.

Is PHP required? If not consider GNU Make. It was especially developed to solve such problems as your. With this simple Makefile:

OUT = app
CFLAGS = -O2 -Wall

$(OUT): main.o

clean:
        rm -rf $(OUT) main.o

You get ability to easy compile your program with different compiler flags and performing clean operations:

make           # for compiling
make clean     # for remove binaries

Make has a good manual. Also, there is similar tool from Microsoft called nmake.
