Question

我有2个arryas，我希望它们交叉并将查找匹配存储到第三个数组中，其值来自第一个数组和第二个数组。第一个数组看起来像这样：

Array
(
    [0] => Array
        (
            [0] => 45
            [1] => 10640
            [2] => 1041-0567041700116
        )

    [1] => Array
        (
            [0] => 46
            [1] => 10640
            [2] => 1041-0567041700318
        )
    [2] => Array
        (
            [0] => 207
            [1] => 10645
            [2] => 03320103000052
        )

和第二个数组：

Array
(
    [0] => Array
        (
            [0] => 03320103000052
            [1] => 0
        )

    [1] => Array
        (
            [0] => 10013800805001
            [1] => 12
        )

    [2] => Array
        (
            [0] => 1090-0360141758201
            [1] => 3
        )

输出应该是：

Array
(
        [0] => Array
            (
                [0] => 207                     =>value from first array
                [1] => 10645                   =>value from first array
                [2] => 03320103000052          =>value from first and second array (this is what i need to compare)
                [3] => 0                       =>value from second array
            )

这类似于this post

但我将数据存储到多维数组

时遇到问题

感谢您提出任何建议和帮助

只能使用两个foreach循环和一个if语句来执行此操作：

$combined = array();
foreach ($array1 as $a) {
    foreach ($array2 as $b) {
        if ($a[2] == $b[0]) {
            $combined[] = array($a[0], $a[1], $a[2], $b[1]);
        }
    }
}

以下是我设置的测试：

<?php
$array1 = array();
$array1[] = array('45', '10640', '1041-0567041700116');
$array1[] = array('46', '10640', '1041-0567041700318');
$array1[] = array('207', '10645', '03320103000052');

$array2 = array();
$array2[] = array('03320103000052', '0');
$array2[] = array('10013800805001', '12');
$array2[] = array('1090-0360141758201', '3');


$combined = array();
foreach ($array1 as $a) {
    foreach ($array2 as $b) {
        if ($a[2] == $b[0]) {
            $combined[] = array($a[0], $a[1], $a[2], $b[1]);
        }
    }
}

print_r($combined);
?>
