ksort

(PHP 3, PHP 4 >= 4.0.0)

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.

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.
