RE: Simple error handling/catching/avoidance

I'm confused. 

Can't you just use method_exists(array("Security", "
getUserDepartment"))?

If that throws an error because of class, then just suppress it (@).

Ok, and, along the lines of this, I also get the following
error/exception when I try to determine if a function is defined using
function_exists():
Fatal error: Undefined class constant 'getUserDepartment' in
/var/www/business/products/attendance.php on line 52

The other difference there is that to call the getUserDepartment()
function, I need to refer to it via another parent/wrapper object:
Security::getUserDepartment()

And, this, again means that I can't really, at runtime, determine if can
call that function, or not.

Stay well
