比较两个数组中的特定数据

array_filter , array_diff 和 array_map

考虑以下示例:

$a = array("a" => "aaa", "b" => "bbb", "c" => "ddd");
$b = array("a" => "aaa", "b" => "bbb", "c" => "ccc");
$arr = array($a,$b); // this is your base array

$find = array("b" => "bbb", "c" => "ccc"); // this is as your options (what you want to find)

现在你可以做:

$barr = array_filter($arr, function($elem) use ($find) {
        return count(array_intersect($find, $elem)) == count($find);
}); // $barr contains only the sub-arrays that contains the option you wanted


$carr = array_map(function($elem) use ($find) {
        return array_diff($elem, $find);
},$barr); // $carr contain only the field that are not in the option array

现在 $carr 是你的欲望输出吗
