krsort

설명

Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.

예 1. krsort() example $fruits = array ("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple"); krsort ($fruits); reset ($fruits); while (list ($key, $val) = each ($fruits)) { echo "$key -> $val\n"; }

This example would display:

fruits[d] = lemon

fruits[c] = apple

fruits[b] = banana

fruits[a] = orange

You may modify the behavior of the sort using the optional parameter sort_flags, for details see sort().
