求一个数组算法
根据 “数组1” 和 “数组2”，得到 “数组3”这样的结果，而且最好能高效点
数组2是设置好的一些属性；数组1是商品可能只填写了某个或某几个属性
//数组1<br />Array<br />(<br /> [100008] => Array<br /> (<br /> [5] => Array<br /> (<br /> [name] => 价格<br /> [0] => 不限<br /> )<br /><br /> [6] => Array<br /> (<br /> [name] => 折扣<br /> [0] => 不限<br /> )<br /><br /> )<br /><br /> [100009] => Array<br /> (<br /> [5] => Array<br /> (<br /> [name] => 价格<br /> [8] => 0-29<br /> )<br /><br /> [6] => Array<br /> (<br /> [name] => 折扣<br /> [13] => 3-5折<br /> )<br /> [7] => Array<br /> (<br /> [name] => 出版社<br /> [20] => 北京大学出版社<br /> )<br /><br /> )<br /><br />)<br /><br />//数组2<br />Array<br />(<br /> [0] => Array<br /> (<br /> [attr_id] => 5<br /> [attr_name] => 价格<br /> [attr_value] => 0-29,30-49,50-99,100以上<br /> )<br /><br /> [1] => Array<br /> (<br /> [attr_id] => 6<br /> [attr_name] => 折扣<br /> [attr_value] => 0-3折,3-5折,5-7折,7-10折<br /> )<br /><br /> [2] => Array<br /> (<br /> [attr_id] => 7<br /> [attr_name] => 出版社<br /> [attr_value] =><br /> )<br /><br />)<br /><br />//得到结果：数组3<br />Array<br />(<br /> [100008] => Array<br /> (<br /> [价格] => 不限<br /> [折扣] => 不限<br /> [出版社] => <br /> )<br /><br /> [100009] => Array<br /> (<br /> [价格] => 0-29<br /> [折扣] => 3-5折<br /> [出版社] => 北京大学出版社<br /> )<br /><br />)
