I have created my own PHP extension in c++ (linux). when zend engine compiles the PHP code am getting the active user functions and internal functions name.

To debug this php extension am using zend_printf to print the values.

Instead of zend_printf wants to write in log file. I checked with FILE I/O, fstream not working here.

How to create the log file in php extension using c/c++?

What I have tried:

I tried with c++ code(FILE *,Ofstream). No error in the code it compiles,but files not getting created in the given location.

When code compiles without error it does not mean that it runs without error. I have not written such PHP extensions so far. But why should opening and writing to a file not work?
All I can think of are the usuals reasons:
Not existing directory part of the file name, no write access to the directory, or no write acces to the file itself if it exists already. I would use the /tmp directory because there usually all users can write.

Perhaps use configuration file for file path, file login, log file rotation etc.
