多Dem php字符串到数组-逗号分隔，冒号分隔的数组 [英] Multi Dem php string to array - comma separated, colon separated array

问题描述

我有一个字符串

$string = 'S:1,M:1,L:1,XL:1,XXL:1,3XL:1';

我想创建一个数组，其中

I want to create an array where

$array['S'] = 1;
$array['M'] = 1;

我以为我会爆炸（’，’，$ string）；
然后爆炸（’：’，$ string）；再次;-)
，但这根本不起作用。

I thought i could explode(',', $string); and then explode(':', $string); again ;-) but that doesn't work at all.

推荐答案

是的，您可以 explode（）两次，但是第二个必须循环：

Yes, you can explode() twice, but the second one has to be in a loop:

$string = 'S:1,M:1,L:1,XL:1,XXL:1,3XL:1';
// Split on the commas
$sizes = explode(",", $string);
// Output array
$quantities = array();

// Loop over the first explode() result
foreach ($sizes as $size) {
  // Assign each pair to $s, $q
  list($s, $q) = explode(":", $size);
  // And put them onto an array keyed by size
  $quantities[$s] = $q;
}

// This builds an array like:
Array
(
    [S] => 1
    [M] => 1
    [L] => 1
    [XL] => 1
    [XXL] => 1
    [3XL] => 1
)
