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.
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";
}
?> |
The above example will output: 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().
