两个数组如何排序一样?
比如:$a=[1,2,3]; $b=[3,2,1];

问题:
如何把$b弄的和$a一样

------解决方案--------------------

PHP code
$a = array(1,2,3);
$b = array(3,2,1);

foreach($a as $v) $r[] = array_search($v, $b);

array_multisort($r, $b);
print_r($b); <div class="clear">
                 
              
              
        
            </div>
