krsort — Sort an array by key in reverse order
Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.
如果成功則回傳 TRUE,失敗則回傳 FALSE。
Example#1 krsort() example
<?php
$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
krsort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val\n";
}
?>
上例將輸出:
d = lemon c = apple b = banana a = orange
You may modify the behavior of the sort using the optional parameter sort_flags , for details see sort().
