[Solved] Where does printf() output go?
This seems like a stupid question, but I can't figure it out. When printf() is called in the PHP code, where is the output?
I found some indication that printf() output is sent to /dev/null, so I'm using log_error() instead. Output goes to /var/log/system.log.
It depends on where the code is being used. If it is a web gui or console program, the output should go there.
