krsort — 对数组按照键名逆向排序
&$array
[, int $sort_flags
= SORT_REGULAR
] )对数组按照键名逆向排序,保留键名到数据的关联。主要用于结合数组。
array
输入的数组。
sort_flags
可以用可选参数 sort_flags
改变排序的行为,详情见 sort() 。
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
Example #1 krsort() 例子
<?php
$fruits = array( "d" => "lemon" , "a" => "orange" , "b" => "banana" , "c" => "apple" );
krsort ( $fruits );
foreach ( $fruits as $key => $val ) {
echo " $key = $val \n" ;
}
?>
以上例程会输出:
d = lemon c = apple b = banana a = orange

To create a natural reverse sorting by keys, use the following function:
<?php
function natkrsort($array)
{
$keys = array_keys($array);
natsort($keys);
foreach ($keys as $k)
{
$new_array[$k] = $array[$k];
}
$new_array = array_reverse($new_array, true);
return $new_array;
}
?>
