I was working now in a new site developed with PHP 5.0.2 and a wonder
came to me:
Is usefull and recommended to unset a class instance when not needed?
Specially when the class was instantiated inside a function and the
function ends. In this case, the system should automatically destroy
the instance (as it is a local var inside a function).
If we manually unset the instance at the end of the function, does
this affect the PHP performance? I mean, will PHP have to do an extra
job unsetting the var?
Also, the same question arises with database results. Is it worth to
call mysql_free_result at the end of a function that uses it? Must
take into consideration that there are lots of functions that use lots
of MySQL results.
Thanks for any comment
