[PHPLIB-DEV] efficiency of table class From: Spruce Weber (sprucely <email protected>)

Please respond to my email address, as I'm currently not subscribed to
phplib-dev.

Correct me if I'm wrong, but aren't PHP function parameters passed by value
by default? If such is the case, then every member function in the table
class that takes a DB object or array as a parameter is creating a copy of
that object and then discarding it as soon as it exits that function's
scope. With large arrays or db results, the overhead is tremendous.

If a function doesn't modify an object or array passed to it, then it should
be safe to pass a reference to it rather than a copy of the object...

function verify_db(&$db){}

Can anyone tell me why this would or would not be a good idea?
