ksort

Description

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

Példa 1. Ksort() example 1  2 $fruits = array ("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple"); 3 ksort ($fruits); 4 reset ($fruits); 5 while (list ($key, $val) = each ($fruits)) { 6  echo "$key -> $val\n"; 7 } 8

This example would display:

  1 
  2 fruits[a] = orange
  3 fruits[b] = banana
  4 fruits[c] = apple
  5 fruits[d] = lemon
  6       

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