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().
See also asort(), arsort(),
krsort(), uksort(),
sort(), natsort(), and
rsort().
Note:
The second parameter was added in PHP 4.
