PHP比较两个数组并获得匹配的值而不是差异 [英] PHP compare two arrays and get the matched values not the difference

问题描述

我正在尝试比较两个数组并仅获取两个数组中存在的值，但不幸的是，我找不到要使用的正确数组函数...

I'm trying to compare two arrays and get only the values that exist on both arrays but, unfortunately, I can't find the right array function to use...

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

但这是因为两个数组的不同.

But it's for the difference of the both arrays.

示例:

$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**");

推荐答案

简单，使用 array_intersect() 代替:

Simple, use array_intersect() instead:

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