这是一道php的题目
<?php
$a = array("11"=>"aa","22"=>"bb","33"=>"cc","44"=>"dd","55"=>"ee","66"=>"ff","77"=>"hh");
$b = array("22","11","33","55","44","66","33");
如何能做到以下的结果，（其中$b集合"33"有两个）
$c = array("22"=>"bb","66"=>"ff","11"=>"aa","33"=>"cc","55"=>"ee","44"=>"dd","33"=>"cc");
要按照$b的顺序出结果

$c = array("22"=>"bb","66"=>"ff","11"=>"aa","33"=>"cc","55"=>"ee","44"=>"dd","33"=>"cc");
这样根本是不可能做到的。
$c = array("22"=>"bb","66"=>"ff","11"=>"aa","33"=>array('cc','cc'),"55"=>"ee","44"=>"dd");
这样就可以做到。。

$c = array("22"=>"bb","66"=>"ff","11"=>"aa","33"=>"cc","55"=>"ee","44"=>"dd","33"=>"cc");
这种有相同键名的数组是生成不了的
只能按照我上面的方式输出啊
