使用 PHP 从查询字符串中获取数组参数

（注意：这是上一个问题的后续，如何在查询字符串中传递数组？，其中我询问了在查询字符串中传递数组的标准方法。）

我现在有一些 PHP 代码需要使用表示查询字符串-查询字符串数组格式是什么样的PHP 能识别吗？我需要做什么特殊的事情来检索该数组吗？

以下似乎不起作用：

查询字符串：

?formparts=[a,b,c]

PHP：

$myarray = $_GET["formparts"];
echo gettype($myarray)

结果：

string

(NOTE: This is a follow up to a previous question, How to pass an array within a query string?, where I asked about standard methods for passing arrays within query strings.)

I now have some PHP code that needs to consume the said query string- What kind of query string array formats does PHP recognize, and do I have to do anything special to retrieve the array?

The following doesn't seem to work:

Query string:

?formparts=[a,b,c]

PHP:

$myarray = $_GET["formparts"];
echo gettype($myarray)

result:

string

您的查询字符串应该如下所示：

?formparts[]=a&formparts[]=b&formparts[]=c

Your query string should rather look like this:

?formparts[]=a&formparts[]=b&formparts[]=c

如果您正在处理查询字符串，您将查看 $_GET 变量。这将包含上一个问题中 ? 之后的所有内容。

所以你要做的几乎与另一个问题相反。

$products = array();
// ... Add some checking of $_GET to make sure it is sane
....
// then assign..
$products = explode(',', $_GET['pname']);

对于每个变量依此类推。我必须在这里给你一个完整的警告，你必须检查 $_GET 变量的内容以确保它是正常的。否则，您的网站将面临被泄露的风险。

If you're dealing with a query string, you are looking at the $_GET variable. This will contain everything after the ? in your previous question.

So what you will have to do is pretty much the opposite of the other question.

$products = array();
// ... Add some checking of $_GET to make sure it is sane
....
// then assign..
$products = explode(',', $_GET['pname']);

and so on for each variable. I must give you a full warning here, you MUST check what comes through the $_GET variable to make sure it is sane. Otherwise you risk having your site compromised.
