将包含带引号的值的逗号分隔字符串转换为具有硬编码键的关联数组的数组

Question

我需要将字符串从这样转换

"name1", "b", "2", "name2", "c", "3", "name3", "b", "2", ....

为这样的数组：

$arr[0]['name'] = "name1";
$arr[0]['char'] = "b";
$arr[0]['qnt'] = "2";

$arr[1]['name'] = "name2";
$arr[1]['char'] = "c";
$arr[1]['qnt'] = "3";

$arr[2]['name'] = "name3";
$arr[2]['char'] = "b";
$arr[2]['qnt'] = "2";

我尝试使用 explode() 将字符串转换为数组，但它无法按需要工作。

Answer 1

$input = '"name1", "b", "2", "name2", "c", "3", "name3", "b", "2"';
$input = str_replace('"', '', $input);
$input = explode(', ', $input);

$output = array();
$i = 0;
while ($i < count($input)) {
    $output[] = array(
        'name' => $input[$i++],
        'char' => $input[$i++],
        'qnt' => $input[$i++]
    );
}

print_r($output);

输出：

Array
(
    [0] => Array
        (
            [name] => name1
            [char] => b
            [qnt] => 2
        )

    [1] => Array
        (
            [name] => name2
            [char] => c
            [qnt] => 3
        )

    [2] => Array
        (
            [name] => name3
            [char] => b
            [qnt] => 2
        )

)

Answer 2

如果你不关心数组键是数字，你可以这样做：

$string = 'name1, b, 2, name2, c, 3, name3, b, 2';
print_r( array_chunk( explode(',', $string), 3 ) );

Answer 3

解析包含带引号的值的 csv 字符串，然后将该平面数组拆分为 3 元素块，然后使用硬编码键伪造关联行。

代码：（演示）

$text = <<<TEXT
"name1", "b", "2", "name2", "c", "3", "name3", "b", "2"
TEXT;

var_export(
    array_map(
        fn($chunk) => array_combine(['name', 'char', 'qnt'], $chunk),
        array_chunk(str_getcsv($text), 3)
    )
);
