Question

I have an array of objects. If I call unset($array), will it unset all objects in the array AND the array or just the array? Let’s assume these objects are referenced nowhere else.

Answer 1

If that array contains the only reference to the object, then yes. Otherwise no. Also, something to keep in mind from the PHP Documentation:

unset() does just what it’s name says
– unset a variable. It does not force immediate memory freeing. PHP’s
garbage collector will do it when it
see fits – by intention as soon, as
those CPU cycles aren’t needed anyway,
or as late as before the script would
run out of memory, whatever occurs
first.
