rsort
Sorts array in place by values in descending order.
Note:
If two members compare as equal, they retain their original order. Prior to PHP 8.0.0, their relative order in the sorted array was undefined.
Note:
This function assigns new keys to the elements in array. It will remove any existing keys that may have been assigned, rather than just reordering the keys.
Note:
Resets array's internal pointer to the first element.
Parameters
- array
-
The input array.
- flags
-
The optional second parameter flags may be used to modify the sorting behavior using these values:
Sorting type flags:
SORT_REGULAR - compare items normally; the details are described in the comparison operators section
SORT_NUMERIC - compare items numerically
SORT_STRING - compare items as strings
SORT_LOCALE_STRING - compare items as strings, based on the current locale. It uses the locale, which can be changed using setlocale
SORT_NATURAL - compare items as strings using "natural ordering" like natsort
SORT_FLAG_CASE - can be combined (bitwise OR) with SORT_STRING or SORT_NATURAL to sort strings case-insensitively
Return Values
Always returns true.
