PHP比较两个数组并得到匹配的值而不是差异

我正在尝试比较两个数组并仅获取两个数组上存在的值，但不幸的是，我找不到正确的数组函数来使用......

我找到了array_diff()功能：http://php.net/manual/en/function.array-diff.php http://php.net/manual/en/function.array-diff.php

但这是因为两个数组的差异。

Example:

$array1 = array("**alpha**","omega","**bravo**","**charlie**","**delta**","**foxfrot**");
$array2 = array("**alpha**","gamma","**bravo**","x-ray","**charlie**","**delta**","halo","eagle","**foxfrot**");

预期输出：

$result = array("**alpha**","**bravo**","**charlie**","**delta**","**foxfrot**");

简单，使用array_intersect() http://www.php.net/manual/en/function.array-intersect.php反而：

$result = array_intersect($array1, $array2);
