Such as: $test ={"A": 1, "B": 3, "C": 2, "D": 1, "E": 1}; Get: $result ={"B": 3, "C": 2, "A": 1, "D": 1, "E": 1}; tried Rsort ($test), No. Very much like the one in SQL statement, can there be a way? Reply content: Such as: $test ={"A": 1, "B"

For example, {code...} is returned. {code...} is shown as follows: $test={"A":1,"B":3,"C":2,"D":1,"E":1}; Get: $ Result = {"B": 3, "C": 2, "A": 1, "D": 1, "E": 1 }; I tried rsort ($ test). No. Like orderby in SQL statements, is there a solution?
