# 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.

成功回傳`TRUE`失敗回傳`FALSE`。

示範 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().

> 備注: The second parameter was added in PHP 4.
