how to erase all elements of an array

Hello...I have a question again for you guys..
I have an array like this:

Array ( [0] => 2006-12-05 [1] => 2006-12-25 )

Question:

1.) how can I remove all of the elements of this array?

$myArray = array();

If you use $arr = array() the values will be removed, but the variable will still exist. If you use unset($arr) the variable will be destroyed.
