【问题描述】：
所以我使用 implode 将 POST 方法的值存储在变量中...
$xaraktiristika = implode(', ', $_POST['tlxar']);
这给了我这个字符串的结果：
Sugar, Sugar-Type, Decaf, Quantity, Extra Syrup
还有第二个：
$choices = implode(', ', $_POST['epiloges_xar']);
这给了我这个字符串的结果：
Medium-sugar, Brown, Yes, Double, No
现在我想将它们组合起来，以便将它们插入到我的数据库中。
我的问题是我可以将这两者结合起来，结果会是这样的
Sugar:Medium-sugar, Sugar-Type:Brown, Decaf:Yes etc.
或者我应该以不同的方式来做吗？如果我的问题没有多大意义，我深表歉意，但我仍在学习所有这些东西，而且英语不是我的母语。呵呵
如果有帮助，这里是代码：
<?php
if (isset($_POST["btn1"])) {
$xaraktiristika = implode(', ', $_POST['tlxar']);
echo $xaraktiristika;
echo"<br>";
$epiloges_string = implode(', ', $_POST['epiloges_xar']);

<?php

?>我想将 $xarakthristika 和 $choices 组合在一个变量中，并将它们插入到数据库中，就像我在文章开头所说的那样。
【问题讨论】：
-
你确定数组的索引总是匹配的吗？
-
你想用输出做什么，看起来有点像JSON。
-
我把代码贴出来以防万一
