比较两个数组并返回相同的值

Question

我有两个数组：

$anna_array = array("soccer" => "10", "basketball" => "20", "tennis" => "30", "atletics" => "40", "volleyball" => "50");
$john_array = array("soccer" => "15", "basketball" => "15", "atletics" => "45");

解释

安娜在足球比赛中的得分是10分，约翰的分数是15分，等等。

我想在两个数组中返回相同的活动。类似于：

安娜活动：足球= 10 -篮球= 20 -马竞= 40。

约翰活动：足球= 15 -篮球= 15 -运动= 45.

有人能帮我吗？

Answer 1

您可以计算数组与array_intersect_key的交集。

$anna_array = array('Soccer' => "10", 'Basketball' => "20", 'Tennis' => "30", 'Atletics' => "40", 'Volleyball' => "50");
$john_array = array('Soccer' => "15", 'Basketball' => "15", 'Atletics' => "45");

$anna_activities = array_intersect_key($anna_array, $john_array);
$john_activities = array_intersect_key($john_array, $anna_array);

演示。
