   proc_close is similar to pclose except that it only works on processes opened by proc_open. proc_close waits for the process to terminate, and returns its exit code. Open pipes to that process are closed when this function is called, in order to avoid a deadlock - the child process may not be able to exit while the pipes are open.

   How do I open and close a process handle?

   • The functions we'll be using to open and close the process handle are proc_open () and proc_close (), which work together. That is, proc_open () opens the process and returns a handle to it, then when you're done you pass that handle to proc_close () to clean up. Of the two, proc_open () is the most difficult, so let's go over that first.

   What does fclose do after a script is sent?

   • After the script has been sent, fclose () needs to be called on the pipe to clean up the resources. The last step is using proc_close () to close the process, but it's important that you only do this if you've already used fclose () to close all your pipes. Failure to do so may cause your script to hang!
