unset($variable)

is something completely different than:

$variable = array()

The first one will just do the unset and leave it to the garbage 
collection to free the memory.
The second one will free the memory immediately by overwriting the old 
content.

Thus the first one will be faster, while the second one will be cheaper.

Depending on the context both might increase or decrease performance.
