 Is there any benefit to setting a pointer to a class instance to null before

 function myfunc ()

  $p = null;

 Thanks.



No!
In this case the GC will do that for you :)

Nope, AFAIK everything inside the function will disappear when the function
exits.  Unless you run into one of the memory release issues talked about in the
past, in that case you might be SOL.

Thanks, I expected that to be the case, but it's not been crucial up to now. 
Rather than having a script that runs for a while and quits, I'm hoping to run 
a small server written in PHP and wanted to be 100% sure that I didn't need to.
