分享两个数组合并不覆盖重复的值
我又两个数组，现在想合并成为一个数组，但是在用foreach(),array_combine之后都是去重了，原数组如下：
合并后的效果是：
不知道这个该怎么弄呢
$a= array("8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27");
$b= array ("5","5","3","3","4","5","5","5","6","6","6","6","6","5","5","5","5","5","5","5");
合并后的效果是：
Array ( [5] => 8 [5] => 9 [3] => 10 [3] => 11 [4] => 12 [5] => 13 [5] => 14 [6] => 15 .......[5] => 27 )

哎，这个不难吧，你想太多了，$arr[$key]就可以直接取出value啊，再说你那个函数完全可以用array_combine($a,$b);嘛，然后通过$key不就吧$value取出来了

徐大斑竹，如果我以$b做key，$a做value的话，那么怎么通过key查找到value呢

相同的key，只会保留最后一个值，否则key一样，你获取哪个值呢？可以把键/值放到一个数组里

你的key一样，肯定去重啊
Array ( [5] => 8 [5] => 9...

你想用 $b 做键，$a 做值。那么同名的键必然都会后者覆盖前者
也就是说，你不可能得到你期望的数组。
因为即便是你手写，也写不出来
你这能生成这样的二维数组
