Given a bunch of mixes variables, I'm in a situation where I can't
know what type they are.
Can I use unset to kill an object? unset($object);
Can I use unset to kill a pointer to an open file? unset($fp);
Can I use unset to kill a pointer to a database return?
unset($mySqlResult);

Dont’ make my mistake. It is costly.
Say you have defined a variable $var in your main script.
Now in a function you access it using:
global $var;
But you want to set it to null inside the function.
DO: $var = null;
DONT DO: unset($var);

Just wondering,
Is it possible for an instance of a class to unset itself?
can I do "unset($this)" or "unset(&$this)"
regards,

Hello,
I've written a small function to delete a variable from a class' internal array.
The variables on their own are custom class objects, and I'm a bit confused about the whole pass by reference thing.
First I'll show you the code:
# removes a parameter from the array.
# variables are passed as reference to prevent overhead.
