ksort – Sort an array by key

Description

bool ksort ( array array [, int sort_flags])

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

Returns TRUE on success or FALSE on failure.

Example 1. ksort() example

<?php
$fruits = array(“d”=>“lemon”, “a”=>“orange”, “b”=>“banana”, “c”=>“apple”);
ksort($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
