You can use krsort "Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays. " like this:

您可以使用krsort“按键对数组进行反向排序，保持键与数据的相关性。这主要用于关联数组。“是这样的:

$myval = array(
    'name1'=>'google', 
    'name5'=>'yahoo', 
    'name3'=>'facebook',
    'name2'=>'twitter',
    'name4'=>'linkedin');

krsort($myval);

print_r($myval);
