在PHP多个阵列寻找共同的价值观
问题描述：
我需要多个阵列找到共同的价值观。阵列的数目可以是无限的。
示例（从输出的print_r ）
I need to find common values in multiple arrays. Number of arrays may be infinite.
Example (output from print_r)
Array1
(
[0] => 118
[1] => 802
[2] => 800
)
Array2
(
[0] => 765
[1] => 801
)
Array3
(
[0] => 765
[1] => 794
[2] => 793
[3] => 792
[4] => 791
[5] => 799
[6] => 801
[7] => 802
[8] => 800
)
现在，我需要找到那些对他们的所有3个（或以上如果可用）......我该怎么做呢？
now, I need to find the values that are common on all 3 (or more if available) of them.... how do I do that?

答
array_intersect()$c$c>
$intersect = array_intersect($array1,$array2,$array3);
如果你不知道你有多少个数组有，然后建立数组和用户call_user_func_array()$c$c>
If you don't know how many arrays you have, then build up an array of arrays and user call_user_func_array()
$list = array();
$list[] = $array1;
$list[] = $array2;
$list[] = $array3;
$intersect = call_user_func_array('array_intersect',$list);
