Question

我有两个数组。

Array-1
    (
        [0] => title,size
        [1] => color
        [2] => length
    )

Array-2
    (
        [size_1] => 100
        [color_1] => 200
        [material_1] => 480
    )

我正在尝试从上面的数组中用php实现下面的数组。

Array
    (
        [title] => 100
        [size] => 100
        [color] => 200
        [length] => 480
    )

Answer 1

一种稍微简单的方法是循环并分解第一个数组的所有值，然后使用数组填充来创建values数组。

$arr = array('title,size', 'color', 'length');
$b = array('size_1' => 100, 'color_1' => 200, 'material_1' => 480);
$b = array_values($b); // since we don't need the keys, just remove them

$result =[];
foreach($arr as $key => $a){
    $temp = explode(",", $a);
    $result = array_merge($result, array_combine($temp, array_fill(0, count($temp), $b[$key])));
}
var_dump($result);

尝试array_combine创建一个新数组，该数组将从array1中获取键，并从array2中获取值，然后使用foreach将它们一起迭代，并产生如下所示的期望结果：

<?php

$a = array('title,size', 'color', 'length');
$b = array('size_1' => 100, 'color_1' => 200, 'material_1' => 480);
$c = array_combine($a, $b);

$result = array();
foreach($c as $key => $val) {
    if(strpos($key, ',')) {
        $temp = explode(',', $key);
        foreach($temp as $keys){
            $result[$keys] = $val;
        }
    } else {
        $result[$key] = $val;
    }
}

echo '<pre>';
print_r($a);
print_r($b);
print_r($c);
print_r($result);

Output

$a = Array
(
    [0] => title,size
    [1] => color
    [2] => length
)
$b = Array
(
    [size_1] => 100
    [color_1] => 200
    [material_1] => 480
)
$c = Array
(
    [title,size] => 100
    [color] => 200
    [length] => 480
)
$result = Array
(
    [title] => 100
    [size] => 100
    [color] => 200
    [length] => 480
)
