Question

所以这可能是一个简单的问题，但我无法确定，我怎样才能获得数组内部的数据？我想从数组数组中的第二个元素中获取最后两个以逗号分隔的值，如果这有意义的话。

我的数组看起来像这样：

 Array
(
[0] => Array
    (
        [0] => Print Date
        [1] => Cost
        [2] => Recipient
        [3] => Status
        [4] => Tracking #/Insurance ID
        [5] => Date Delivered
        [6] => Carrier
        [7] => Class Service
        [8] => Special Services
        [9] => Insured Value
        [10] => Cost Code
        [11] => Weight
        [12] => Mail Date
        [13] => Refund Type
    )

[1] => Array
    (
        [0] => 1/20/2016
        [1] => $8.15
        [2] => Justin De Los Polive, PO BOX 2353, BLANCO, TX 78606-1232
        [3] => Printed
        [4] => ="9405511"
        [5] => 
        [6] => USPS
        [7] => Priority Mail (R)
        [8] => USPS Tracking
        [9] => 
        [10] => 
        [11] => 1lb 8oz
        [12] => 1/20/2016
        [13] => E-refund
    )

[2] => Array
    (
        [0] => 1/20/2016
        [1] => $8.15
        [2] => Kist Benings, PO BOX 126, SPECULATOR, NY 12164-0026
        [3] => Printed
        [4] => ="9405511899563327"
        [5] => 
        [6] => USPS
        [7] => Priority Mail (R)
        [8] => USPS Tracking
        [9] => 
        [10] => 
        [11] => 1lb 8oz
        [12] => 1/20/2016
        [13] => E-refund
    )

[3] => Array
    (
        [0] => 1/20/2016
        [1] => $8.92
        [2] => billy flyn, PO BOX 696, P.O. BOX 696, WESTCLIFFE, CO 81252-1696
        [3] => Printed
        [4] => ="94063388113621"
        [5] => 
        [6] => USPS
        [7] => Priority Mail (R)
        [8] => USPS Tracking
        [9] => 
        [10] => 
        [11] => 1lb 8oz
        [12] => 1/20/2016
        [13] => E-refund
    )

我希望能够在第二个元素（即状态和城市）中抓取最后两个以逗号分隔的值，并将它们放入自己的元素中，这样看起来像这样：

[2] => Array
    (
        [0] => 1/20/2016
        [1] => $8.15
        [2] => Kist Benings, PO BOX 126, 
        [3] => SPECULATOR 
        [4] => NY 12164-0026
        [5] => Printed
        [6] => ="9405511899563327"
        [8] => 
        [9] => USPS
        [10] => Priority Mail (R)
        [11] => USPS Tracking
        [12] => 
        [13] => 
        [14] => 1lb 8oz
        [15] => 1/20/2016
        [16] => E-refund
    )

我的代码：

<?php

function csv_to_array($filename='', $delimiter=',')
{
    if(!file_exists($filename) || !is_readable($filename))
        return FALSE;

    $header = NULL;
    $data = array();
    if (($handle = fopen($filename, 'r')) !== FALSE)
    {
        while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE)
        {
            if(!$header)
                $header = $row;
            else
                $data[] = array_combine($header, $row);
        }
        fclose($handle);
    }
    return $data;
}

echo "<pre>";
print_r(csv_to_array('PrintHistory.csv'));
echo "</pre>";

die();
?>

Answer 1

如果Recipient格式相当一致：

foreach(array_column($csv, 2) as $val) {
    preg_match('/(\w+), (\w{2}) [\d-]+$/', $val, $matches);
    $city  = isset($matches[1]) ? $matches[1] : 'none';
    $state = isset($matches[2]) ? $matches[2] : 'none';
}

array_column()从内部数组中获取所有2索引的数组。
循环该数组。
正则表达式应该得到城市和州。

您可能需要在循环之前执行$something = array_column()然后unset($something[0]);以删除标头数组。

假设记录是一致的：

取Recipient并将其爆炸。输出记录是使用数组切片构建的。

笨拙，但它确实起作用......

working demo...

守则：

// output in here
$out = array();

// lose first record...
array_shift($data);

foreach ($data as $details) {

    $recipient = explode(',', $details[2]);

    $outRec = array_merge(
                array_slice($details, 0, 2),

                 array($recipient[0] .', '. $recipient[1]),
                 array_slice($recipient, 2, 1),
                 array_slice($recipient, 3, 1),

                 array_slice($details, 3)
            );

     $out[] = $outRec;
}

数组内部的数组元素
