从一个多维数组中获取值，并基于来自第一键的匹配值将其放入另一个多维数组中

Question

我有两个数组，$FULL_LIST和$ONLY_TITLES根据第一个键匹配值。

$FULL_LIST:

Array
(
    [0] => Array
        (
            [0] => samsung-a40 
            [1] => Samsung A40 Phone
            [2] => 
            [3] => 21
            [4] => 334234
            [5] => 0          
        )

    [1] => Array
        (
            [0] => samsung-a72
            [1] => Galaxy A72 Phone
            [2] => 
            [3] => 230
            [4] => 239049
            [5] => 0    
        )
    [2] => Array
        (
            [0] => lg-k61
            [1] => LG K61 Phone 
            [2] => 
            [3] => 22
            [4] => 249582
            [5] => 0    
        )


  etc...

$only_titles:

Array
(
    [0] => Array
        (
            [0] => samsung-a40 
            [1] => Black Phone Case For Samsung A40               
        )

    [1] => Array
        (
            [0] => lg-k61
            [1] => Red Case LG K61 Phone            
        )

    [2] => Array
        (
            [0] => samsung-a72
            [1] => Folding Phone Case for Galaxy A72 Phone          
        )
   
  etc...

我想从$only_title数组（其基本的长乘积标题）的第二个键中取值，并将其替换到$full_list数组中：

$final_result:

Array
(
    [0] => Array
        (
            [0] => samsung-a40
            [1] => Black Phone Case For Samsung A40   // title from $only_titles
            [2] => 
            [3] => 21
            [4] => 334234
            [5] => 0          
        )

    [1] => Array
        (
            [0] => samsung-a72
            [1] => Folding Phone Case for Galaxy A72 Phone   // title from $only_titles     
            [2] => 
            [3] => 230
            [4] => 239049
            [5] => 0    
        )
    [2] => Array
        (
            [0] => lg-k61
            [1] => Red Case LG K61 Phone  // title from $only_titles
            [2] => 
            [3] => 22
            [4] => 249582
            [5] => 0    
        )
  etc...

我尝试过array_replace_recursive()，但问题是它期望子数组的顺序是相同的。但是，正如您在两个数组中所看到的，第二个子数组并不匹配。在array_replace_recursive()中，第二个子数组错误：

[1] => Array
    (
        [0] => samsung-a72
        [1] => Red Case LG K61 Phone  // this is wrong
        [2] => 
        [3] => 230
        [4] => 239049
        [5] => 0    
    )

如何检查来自第一个键的值是否匹配？

这个脚本将帮助您解决问题

<?php

$full_array = [
    [
        'samsung-a40',
        'Samsung A40 Phone',
        null,
        21,
        334234,
        0,
    ],
    [
        'samsung-a72',
        'Galaxy A72 Phone',
        null,
        230,
        239049,
        0,
    ],
];

$only_titles = [
    [
        'samsung-a40',
        'Black Phone Case For Samsung A40',
    ],
    [
        'samsung-a72',
        'Red Case LG K61 Phone  ',
    ],
];

$formattedOnlyTitles = [];
foreach ($only_titles as $value) {
    $formattedOnlyTitles[$value[0]] = $value[1];
}

$fullArrayWithNewTitle = [];
foreach ($full_array as $value) {
    if (isset($formattedOnlyTitles[$value[0]])) {
        $value[1] = $formattedOnlyTitles[$value[0]];
    }

    $fullArrayWithNewTitle[] = $value;
}

print_r($fullArrayWithNewTitle);

输出

Array
(
    [0] => Array
        (
            [0] => samsung-a40
            [1] => Samsung A40 Phone
            [2] => 
            [3] => 21
            [4] => 334234
            [5] => 0
        )

    [1] => Array
        (
            [0] => samsung-a72
            [1] => Galaxy A72 Phone
            [2] => 
            [3] => 230
            [4] => 239049
            [5] => 0
        )
)

首先，我更改title_onlyvar的格式，以便在下一个foreach中使用它

$formattedOnlyTitles = [];
foreach ($only_titles as $value) {
    $formattedOnlyTitles[$value[0]] = $value[1];
}

在下一个foreach中，我只使用新格式化的title_only数组检查标题

if (isset($formattedOnlyTitles[$value[0]])) {
    $value[1] = $formattedOnlyTitles[$value[0]];
}

如果需要的话，可以更改标题
