Question

I’m a php developer as well as cpp developer. I was wondering: if I make a cpp binary and I run it on php. Will that make my process run faster?

For example:

I have to compare 1,000 array elements and execute a process for each of them and in some cases I had to run it over and over again ( recursively) . Yes is messup but it works !.

Answer 1

1. Yes, this might be faster. It’s also very hard to do right (lots of corner cases in IPC).
2. Don’t try this unless it’s absolutely necessary for performance. First try to improve the algorithm in PHP.
3. Don’t use the C++ code in production until you’ve measured the difference, and the C++ solution is significantly faster.
4. Don’t run a binary, write a library and link it into the PHP interpreter. PHP is implemented in C, so export your C++ functions to C using extern "C".
