我需要找到多維數組之間的差異多維數組的區別
我有數組是這樣的:
$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')
),
),
);
$arr2 = array(
'test1' => array(
'XXX' => array(
'w1' => array('id' => '5'),
'w2' => array('id' => '2'),
'w3' => array('id' => 'g'),
'w4' => array('id' => 'x'),
),
'YYY' => array(
'w1' => array('id' => '4'),
'w2' => array('id' => '1')
),
'ZZZ' => array(
'w1' => array('id' => '3'),
'w2' => array('id' => '9')
),
),
);
,我需要刪除重複,但我需要比第一級密鑰,二級密鑰和去年水平鍵,值對,所以我的結果應該是這樣的
array(
'test1' => array(
'XXX' => array(
'w4' => array('id' => 'x'),
),
)
我嘗試使用
function check_key($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");
但是這個函數不會比較上一級的最後一級鍵值對。 我會尋求幫助
