Rsort () Definition and usage
The Rsort () function reverses the order of 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 delete the original key name and not just reorder it.
Returns TRUE if successful, otherwise FALSE.
The Second optional parameter contains a different sort flag.
Grammar
Rsort (array,sorttype) parameter description
Array required. The input array.
SortType is optional. Specifies how the values of the array are arranged. Possible values:
Sort_regular-Default. Processed in their original type (without changing the type).
Sort_numeric-Handle the value as a number
Sort_string-handles the value as a string
Sort_locale_string-handles the value as a string, based on local settings *.
*: This value is new for PHP 4.4.0 and 5.0.2. Prior to PHP 6, the system's locale was used, which can be changed using setlocale (). From PHP 6, you must use the I18n_loc_set_default () function.
