将数组值与先前的数组值进行比较

Question

如何将当前数组值与之前的数组值进行比较。示例如果我有以下数组并希望将[BM1367 PD C 70] [ST00576] ['transferfrom']与之前的数组进行比较[BM1367 PD B 85] [ST00576] ['transferfrom']？

    [BM1367    PD  B  85] => Array
        (
            [ST00576] => stdClass Object
                (

                    [transferto] => 66
                    [BR_ID] => 102

Answer 1

您有一个STD class objects数组，在这种情况下，您可以按如下方式比较元素： 假设您提供的数组位于另一个数组

中

$tempArray = {


        [BM1367    PD  B  85] => Array
            (
                [ST00576] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 102
                        [refno] =>  

                    )

                [OT01606] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 66
                        [refno] => 102 - ST00576

                    )

            )

        [BM1367    PD  C  70] => Array
            (
                [ST00576] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 102
                        [refno] =>  

                    )

                [OT01606] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 66
                        [refno] => 102 - ST00576

                    )

            )

        [BM1367    PD  C  85] => Array
            (
                [ST00576] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 102
                        [refno] =>  

                    )

                [OT01606] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 66
                        [refno] => 102 - ST00576

                    )

            )

        [BM1367    PD  D  85] => Array
            (
                [ST00576] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 102
                        [refno] =>  

                    )

                [OT01606] => stdClass Object
                    (
                        [transferfrom] => 102
                        [transferto] => 66
                        [BR_ID] => 66
                        [refno] => 102 - ST00576

                    )

            )

    )

};

您现在可以访问元素

$tempArray['BM1367 PD C 70']['ST0076']->transferfrom

$tempArray['BM1367 PD B 85']['ST0076']->transferfrom

并且为了比较它们

(int)$tempArray['BM1367 PD C 70']['ST0076']->transferfrom == (int)$tempArray['BM1367 PD B 85']['ST0076']->transferfrom

你问：

  

如何将当前数组值与先前的数组值进行比较

我想你可能想看看下面的PHP函数

1. current（） - http://www.php.net/manual/en/function.current.php
2. prev（） - http://www.php.net/manual/en/function.prev.php
3. next（） - http://php.net/manual/en/function.next.php

例如：

<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport);    // $mode = 'bike';
$mode = next($transport);    // $mode = 'car';
$mode = prev($transport);    // $mode = 'bike';
$mode = end($transport);     // $mode = 'plane';
?>

我能够在计算公式上使用它们，工作很棒！在比较您的上一个或下一个数组的当前值时，它也很有用。
