Question

我需要比较两个数组：

第一个数组包含zipcodes keys和dates values：

Array ( [1000] => Array ( [0] => 2014-12-01 am [1] => 2014-12-01 pm [2] => 2014-12-05 am [3] => 2014-12-05 pm [4] => 2014-12-08 am [5] => 2014-12-08 pm [6] => 2014-12-12 am [7] => 2014-12-12 pm [8] => 2014-12-15 am [9] => 2014-12-15 pm [10] => 2014-12-19 am [11] => 2014-12-19 pm [12] => 2014-12-22 am [13] => 2014-12-22 pm ) [1020] => Array ( [0] => 2014-12-01 am [1] => 2014-12-01 pm [2] => 2014-12-02 am [3] => 2014-12-02 pm [4] => 2014-12-05 am [5] => 2014-12-05 pm [6] => 2014-12-08 am [7] => 2014-12-08 pm [8] => 2014-12-09 am [9] => 2014-12-09 pm [10] => 2014-12-12 am [11] => 2014-12-12 pm [12] => 2014-12-15 am [13] => 2014-12-15 pm [14] => 2014-12-16 am [15] => 2014-12-16 pm [16] => 2014-12-19 am [17] => 2014-12-22 am [18] => 2014-12-22 pm [19] => 2014-12-23 am [20] => 2014-12-23 pm ) (...) )

然后第二个数组的日期在数据库中至少存储了4次，如下例所示：

Array ( [0] => 2014-12-01 pm [1] => 2014-12-12 am )

我正在尝试使用array_diff创建一个没有此日期的新数组，但它不起作用。

我错过了什么？任何想法如何使这项工作？

提前致谢

Answer 1

所以，目前你有一个不必要的数组嵌套。

看看第一个条目：

<?php
$dates = array(
'1000' => array(
    array('2014-12-01 am', '2014-12-01 pm', '2014-12-05 am', '2014-12-05 pm', '2014-12-08 am', '2014-12-08 pm', '2014-12-12 am', '2014-12-12 pm', '2014-12-15 am', '2014-12-15 pm', '2014-12-19 am', '2014-12-19 pm', '2014-12-22 am','2014-12-22 pm')
)
....

你可以这样：

<?php
$dates = array(
'1000' => array('2014-12-01 am', '2014-12-01 pm', '2014-12-05 am', '2014-12-05 pm', '2014-12-08 am', '2014-12-08 pm', '2014-12-12 am', '2014-12-12 pm', '2014-12-15 am', '2014-12-15 pm', '2014-12-19 am', '2014-12-19 pm', '2014-12-22 am','2014-12-22 pm'),
....

如果您打算使用array_diff，那么您必须迭代$ date来比较其中的每个值。（此代码仅在没有嵌套数组的情况下有效。）

<?php
foreach($dates as $key => value){
  $dates[$key] = array_diff($value, $delivery_dates_db);
}

此代码应与嵌套数组一起使用。

<?php
foreach($dates as $key => value){
  $dates[$key] = array_diff($value[0], $delivery_dates_db);
}

我不确定你为什么要嵌套另一个数组。

将2个数组与array_diff进行比较
