如何在PHP中按字符将数组拆分为关联数组

问题描述

我构建了一个程序，该程序从充满字符串的数组中获取数据，然后将数据转换为适当格式的数组。这是原始数组：

var maximizeButton = view.down('[type="maximize"]')
if (maximizeButton) {
    maximizeButton.setBind({
        disabled: '{!isMaxWinAllowed}'
    });
}

这是数据格式正确的新数组。

$arr = array(
    "action: Added; quantity: 1; item_code: RNA1; product_name: Mens Organic T-shirt; colour: White; size: XL","action: Subtracted; quantity: 7; item_code: RNC1; product_name: Kids Basic T-shirt; colour: Denim Blue; size: 3-4y","action: Added; quantity: 20; item_code: RNV1; product_name: Gift Voucher; style: Mens; value: £20",);

在这里，我认为我应该将数组更改为关联的键值对数组，并认为如果我能找到一种方法，可以通过将字符分割为数组将其转换为所述的关联数组，则相对简单，在这种情况下为“：”。

最后，我希望数组看起来像这样：

Array
(
    [0] => Array
        (
            [0] => action: Added
            [1] => quantity: 1
            [2] => item_code: RNA1
            [3] => product_name: Mens Organic T-shirt
            [4] => colour: White
            [5] => size: XL
        )

    [1] => Array
        (
            [6] => action: Subtracted
            [7] => quantity: 7
            [8] => item_code: RNC1
            [9] => product_name: Kids Basic T-shirt
            [10] => colour: Denim Blue
            [11] => size: 3-4y
        )

    [2] => Array
        (
            [12] => action: Added
            [13] => quantity: 20
            [14] => item_code: RNV1
            [15] => product_name: Gift Voucher
            [16] => style: Mens
            [17] => value: £20
        )

)

...等等。

我曾尝试使用array_column和array_combine函数，但在PHP相对较新的地方我运气并不好。 任何帮助将不胜感激！

解决方法

搜索替换后，您可以使用parse_str。

<?php

$arr = array(
    "action: Added; quantity: 1; item_code: RNA1; product_name: Mens Organic T-shirt; colour: White; size: XL","action: Subtracted; quantity: 7; item_code: RNC1; product_name: Kids Basic T-shirt; colour: Denim Blue; size: 3-4y","action: Added; quantity: 20; item_code: RNV1; product_name: Gift Voucher; style: Mens; value: £20",);

$arr = array_map(function($v) {
    parse_str(str_replace([': ','; '],['=','&'],$v),$result);
    return $result;
},$arr);

var_export($arr);

输出：

array (
  0 => 
  array (
    'action' => 'Added','quantity' => '1','item_code' => 'RNA1','product_name' => 'Mens Organic T-shirt','colour' => 'White','size' => 'XL',),1 => 
  array (
    'action' => 'Subtracted','quantity' => '7','item_code' => 'RNC1','product_name' => 'Kids Basic T-shirt','colour' => 'Denim Blue','size' => '3-4y',2 => 
  array (
    'action' => 'Added','quantity' => '20','item_code' => 'RNV1','product_name' => 'Gift Voucher','style' => 'Mens','value' => '£20',)
