我需要找到多维数组之间的区别
我有这样的数组:
$arr1 = array(
'test1' => array(
'XXX' => array(
'w1' => array('id' => '5'),
'w2' => array('id' => '2'),
'w3' => array('id' => 'g'),
),
'YYY' => array(
'w1' => array('id' => '4'),
'w2' => array('id' => '1')
),
'ZZZ' => array(
'w1' => array('id' => '3'),
'w2' => array('id' => '9')
),
'QQQ' => array(
'w1' => array('id' => '3'),
'w2' => array('id' => '9')
),
),
'test2' => array(
'XXX' => array(
'w1' => array('id' => '8'),
'w2' => array('id' => '3')
),
'YYY' => array(
'w1' => array('id' => '15'),
'w2' => array('id' => '1')
),
'ZZZ' => array(
'w1' => array('id' => '5'),
'w2' => array('id' => '2')
),
),
);
$arr2 = array(
'test1' => array(
'XXX' => array(
'w1' => array('id' => '5'),
'w2' => array('id' => '2'),
'w3' => array('id' => 'g'),
'w4' => array('id' => 'x'),
),
'YYY' => array(
'w1' => array('id' => '4'),
'w2' => array('id' => '1')
),
'ZZZ' => array(
'w1' => array('id' => '3'),
'w2' => array('id' => '9')
),
),
);
我需要删除重复项,但我需要比较第一级键,第二级键和最后一级键,值对,所以我的结果应该是那样
array(
'test1' => array(
'XXX' => array(
'w4' => array('id' => 'x'),
),
)
我尝试使用
function check_key($a,$b) {
if ($a===$b)
{
return 0;
}
return ($a>$b)?1:-1;
}
function check_value($a,$b) {
if ($a===$b)
{
return 0;
}
return ($a>$b)?1:-1;
}
$merged_arr = array_udiff_uassoc($arr2,$arr1,"check_key","check_value");
但是这个功能不能比较最后一级的最后一级键值对。
答案 0 :(得分:1)
尝试使用此功能。我认为这会对您有所帮助。
$result[] = array_diff_key($arr1, $arr2);
print_r($result);
