illustrate

The rsort() function reverses the elements of the array by key values. The function is basically the same as arsort() .

Note: This function assigns a new key name to the cells in the array . This will remove the original key name instead of reordering.

Return TRUE if successful, otherwise return FALSE.

The optional second parameter contains additional sorting flags.
