Kelly,
The structure of your application will determine how much of an
issue this is. If you throw together a bunch of code and call a bunch
of functions that have been designed on the fly this can be an issue.
However, if you build small, testable pieces of code that are concise
and easy to understand, the negative implications of not having a
defined return type are very minimal. FWIW, I'm actually a proponent of
being able to define the return type (for objects) but it's never really
been an overly a significant issue for me.

I can make up a return variable name on the fly,

This one could be useful - auto declaring a variable, yet it would still
have a "locked" data type.

I can also change the type of data the function returns without having
to
change the variable definitions everywhere the function is called.

This is the dangerous one Joe is talking about. This will only cause
you
heart ache down the road IMO :-)

When I write a PHP function, I can make up a return variable name on
the
fly, and it doesn't matter if I'm returning characters, numbers, or
arrays.

Similarly, when I call a PHP function, I can make up a variable name
on the
fly to receive the output, and it doesn't matter what kind of output
is
being passed back.

But, if you want to call it laziness, guilty as charged. ;-)
