数组问题 求大侠给个方法
$a = Array
(
[0] => 3
[1] => 1
[2] => 2
[3] => 7
)
$b = Array
(
[1] => Emross War
[2] => Roman Empire
[3] => Avalon Wars
[7] => 掌上三国
[9] => 罗马（91）
[10] => Space Dominions
[11] => 腾讯三国
[12] => Vampire War
[15] => 三国英雄传
[17] => 掌上水浒
)
$a数组中的值是$b 的键值
那我如何得到
$c = Array
(
[1] => Emross War
[2] => Roman Empire
[3] => Avalon Wars
[7] => 掌上三国
)

17 =>'掌上水浒'
);
foreach($a as $k){
$c[$k]=$b[$k];
}
ksort($c);
print_r($c);sort($a); // 将数组 $a 按值升序排列
$c = array(); //定义一个结果数组
foreach($a as $k) { // 依次从数组 $b 中取值
$c[$k] = $b[$k];
}
$a = Array
(
'0' => 3,
'1' => 1,
'2' => 2,
'3' => 7

$c = array_flip($a); //array_flip -- 交换数组中的键和值
