ksort

(PHP 3, PHP 4 >= 4.0.0)

ksort -- Sort an array by key

Description

int ksort ( array array [, int sort_flags])

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

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

This example would display:

a = orange b = banana c = apple d = lemon

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