This function sorts an array. Elements will be arranged from
|
|
lowest to highest when this function has completed.

<simpara>
|
|
This function assigns new keys for the elements in
|
|
<parameter>array</parameter>. It will remove any existing
|
|
keys you may have assigned, rather than just reordering the keys.
