If you're just adding to an array using the '$arr[]' construct, then 
PHP will increment the index for you. But, let's say you're getting 
information out of a database and each record is uniquely identified 
by an ID number in the database. If you use that ID number as the 
index when you store the record in the array, the order you store 
them may not be in ascending  order according to that number.
