是否有一个 PHP 函数可以接受多个数组(每个数组代表单个字段值的集合，例如名字)并输出一个数组，该数组的值将这些字段组合在一起？
例如:
$arr1 = ['John', 'Kyle']; // first names
$arr2 = ['Smith', 'Andrews']; // last names
$arr3 = ['<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f19b9e999fb19489909c819d94df929e9c" rel="noreferrer noopener nofollow">[email protected]</a>', '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ec87958089ac89948d819c8089c28f8381" rel="noreferrer noopener nofollow">[email protected]</a>']; // email addresses
// ...
Output:
Array(
0 => ['John', 'Smith', '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a0cacfc8cee0c5d8c1cdd0ccc58ec3cfcd" rel="noreferrer noopener nofollow">[email protected]</a>'],
1 => ['Kyle', 'Andrews', '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a1cad8cdc4e1c4d9c0ccd1cdc48fc2cecc" rel="noreferrer noopener nofollow">[email protected]</a>'],
)
最佳答案
您可以使用array_map()以 null 作为第一个参数来合并它们...
NULL can be passed as a value to callback to perform a zip operation on multiple arrays. If only array1 is provided, array_map() will return the input array.
所以
print_r(array_map(null, $arr1, $arr2, $arr3));
给...
Array
(
[0] => Array
(
[0] => John
[1] => Smith
[2] => <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="72181d1a1c32170a131f021e175c111d1f" rel="noreferrer noopener nofollow">[email protected]</a>
)
[1] => Array
(
[0] => Kyle
[1] => Andrews
[2] => <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="402b392c25002538212d302c256e232f2d" rel="noreferrer noopener nofollow">[email protected]</a>
