(PHP3 , PHP4 )

rsort -- Sort an array in reverse order

Description

void rsort (array array [, int sort_flags])

This function sorts an array in reverse order (highest to lowest).

Example 1. Rsort() example


$fruits = array ("lemon", "orange", "banana", "apple");
rsort ($fruits);
reset ($fruits);
while (list ($key, $val) = each ($fruits)) {
    echo "$key -> $val\n";
}
      

This example would display:


fruits[0] = orange
fruits[1] = lemon
fruits[2] = banana
fruits[3] = apple
      

The fruits have been sorted in reverse alphabetical order.
