所以我们假设我们有两个数组:
$x = array(
"id" => 12,
"name" => "Joe",
"surname" => "Murphy",
"age" => 52
);
$y = array(
"id" => 12,
"name" => "Joe",
"surname" => "Murphy",
"age" => 53
);
function key_compare_func($key1, $key2)
{
if ($key1 == $key2)
return 0;
else if ($key1 > $key2)
return 1;
else
return -1;
}
var_dump(array_intersect_ukey($x, $y, 'key_compare_func'));
这将返回$ x
中的所有匹配元素array(4) {
["id"]=> int(12)
["name"]=> string(3) "Joe"
["surname"]=> string(6) "Murphy"
["age"]=> int(52)
}
我只需要["age"]=> int(52)
我看了这些,但似乎没有提供这种功能,除非我错过了一些东西:
array_ udiff_ ASSOC, array_ uintersect_ ASSOC, array_ uintersect_ uassoc,
array_ udiffarray_ uintersect, array_ udiff_ uassoc
答案 0 :(得分:1)
http://php.net/manual/en/function.array-diff-assoc.php
var_dump(array_diff_assoc($x, $y));
