<?php $a1=array("a","b","c","d");
$a2=array("Cat","Dog","Horse","Cow");
print_r(array_combine($a1,$a2));
?>

如果两个数组的个数一致且数组1和数组2的值相对应的话,直接用循环就可以搞定了吧。
下面是我测试用的代码,测试过没有问题的。

<code><?php $a = array('a', 'b', 'c', 'd');
$b = array('1', '2', '3', '4');
$c = array();
for($i=0,$l=count($b);$i<$l;$i++) {
    $c[$a[$i]] = $b[$i];
}
print_r($c);
?>
