相交数目不详的PHP数组 [英] Intersect unknown number of arrays in PHP

问题描述

我想相交PHP数组的任意数，计数这取决于用户提供的参数，每个都可以有任意数量的元素。

I'm trying to intersect an arbitrary number of PHP arrays, the count of which depends on a user provided parameter, each of which can have any number of elements.

例如：
ARRAY1（1，2，3，4，5）
数组2（2，4，6，8，9，23）
ARRAY3（A，B，3，C，F）
...
arrayN（X1，X2，X3，X4，X5 ...... xn）映射

For example: array1(1, 2, 3, 4, 5) array2(2, 4, 6, 8, 9, 23) array3(a, b, 3, c, f) ... arrayN(x1, x2, x3, x4, x5 ... xn)

由于array_intersect需要PARAMS的名单，我不能建立一个阵列阵列相交，并有工作我身边这样的。我想这个解决方案：<一href=\"http://bytes.com/topic/php/answers/13004-array_intersect-unknown-number-arrays\">http://bytes.com/topic/php/answers/13004-array_intersect-unknown-number-arrays但这并没有工作，因为一个错误报道，array_intersect需要2个或更多PARAMS。

Since array_intersect takes a list of params, I can't build one array of arrays to intersect and have to work my way around this. I tried this solution: http://bytes.com/topic/php/answers/13004-array_intersect-unknown-number-arrays but this did not work, as an error is reported that array_intersect requires 2 or more params.

没有人有任何想法如何处理这个的方式尽可能简单？

Does anyone have any idea how to approach this in a manner as simple as possible?

推荐答案

创建一个新的空数组，添加每个阵列的，那么使用的 call_user_func_array（）

Create a new empty array, add each of your arrays to that, then use call_user_func_array()

$wrkArray = array( $userArray1,
                   $userArray2,
                   $userArray3
                 );
$result = call_user_func_array('array_intersect',$wrkArray);
