In my previous blog post I mentioned that the 1.5.0 release of the MongoDB driver for PHP has improved notification support using the PHP Notification API , and showed off a fairly useless (but fun) progress bar. Now its time for a little bit more practical examples using this system: Query logging and profiling. Those of you who clicked through to the github Pull Request may have noticed the long long description of the API and noticed all the different " MONGO_STREAM_NOTIFY_LOG_xxx " constants it included..

The  context  key takes a Stream Context , and is assigned to all of the underlaying connections the driver creates - which means you can set any of the Socket Context  and SSL Context  options and it will Just Work (maaan.. that saved me a ton of work..

When PHP reads from the http stream it will tell you if it came across a " redirect header ...
