ksort
(PHP 3, PHP 4 )
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 <?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().

krsort(), uksort(),

Note:
The second parameter was added in PHP 4.
