两个数组处理

Question

$a=Array
(
    [businessaddressstreet] =0
    [homeaddresspostalcode] =1
    [firstname] =2
    [homeemailaddress] =3
    [workemailaddress] =4
    )另一个数组
$b=Array
(
    [0] =Array
        (
            [0] =wqeqe
            [1] =wer
            [2] =wer
            [3] [email protected]
            [4] =eqee
          )    [1] =Array
        (
            [0] =werwer
            [1] =tert
            [2] =tert
            [3] [email protected]
            [4] =rwe
        )    [2] =Array
        (
            [0] =wer
            [1] =ertert
            [2] =ertet
            [3] [email protected]
            [4] =dasd
        )    )
处理b这个数组使他为：
$b=Array
(
    [0] =Array
        (
            [businessaddressstreet] =wqeqe
            [homeaddresspostalcode] =wer
            [firstname] =wer
            [homeemailaddress] [email protected]
            [workemailaddress] =eqee
          )    [1] =Array
        (
            [businessaddressstreet] =werwer
            [homeaddresspostalcode] =tert
            [firstname] =tert
            [homeemailaddress] [email protected]
            [workemailaddress] =rwe
        )    [2] =Array
        (
            [businessaddressstreet] =wer
            [homeaddresspostalcode] =ertert
            [firstname] =ertet
            [homeemailaddress] [email protected]
            [workemailaddress] =dasd
        )    )
求大侠给解决一下，thanks

Answer 1

foreach($b as $t) {
  foreach($a as $k=>$v) {
    $p[$k] = $t[$v];
  }
  $r[] = $p;
}$b = $r;//或
$a = array_flip($a);
foreach($b as $v) {
  $r[] = array_combine($a, $v);
}$b = $r;

Answer 2

$a = array( 'businessaddressstreet' => 0, 
'homeaddresspostalcode' => 1, 
'firstname' => 2, 
'homeemailaddress' => 3, 
'workemailaddress' => 4);
$keys = array_keys($a);
$b = array( array('wqeqe', 'wer', 'wer', '[email protected]', 'eqee'), 
array('werwer', 'tert', 'tert', '[email protected]', 'rwe'), 
array('wer', 'ertert', 'ertet', '[email protected]', 'dasd'));$num = count($b);
$c = array();
foreach($b as $k => $v){
$c[] = array_combine($keys, $v);
}echo '<pre>';print_r($c);

本人比较笨，用了个很土的方法，感觉还有很多效率高的方法，关注一下！下面例子测试通过！
foreach($a as $key=>$value)
  {
   foreach($b as $key1=>$value1)
   {
   foreach($value1 as $key2=>$value2)
   {
   if($value === $key2)
   {
   unset($b[$key1][$key2]);
   $b[$key1][$key] = $value2;
   }
   }
   }
  }
