ksort

(PHP 3, PHP 4 , PHP 5)

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.

Geeft TRUE terug bij succes, FALSE indien er een fout is opgetreden.

Voorbeeld 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, for details see sort().

See also asort(), arsort(), krsort(), uksort(), sort(), natsort(), and rsort().

Opmerking: The second parameter was added in PHP 4.
