如何通过一个数组中得到PHP？

问题描述：

$idArray = array(1,2,3,4);

我可以写在HTML这一行？

can I write this line in HTML?

<form method='POST' action='{$_SERVER['PHP_SELF']}?arr={$idArray}'>

或者我应该写：

<form method='POST' action='{$_SERVER['PHP_SELF']}?arr[]={$idArray}'>

如何将它传递？

我应该怎么处理它在叫页面？

how should I handle it in the called page?

谢谢！

如果你想传递一个数组作为参数，你就必须添加参数为每个元素。您的查询字符串将变成：

If you want to pass an array as parameter, you would have to add a parameter for each element. Your query string would become:

?arr[]=1&arr[]=2&arr[]=3&arr[]=4

正如其他人写的，你也可以的连载的和的反序列化的数组。

但你真的需要再次进行数据发送到客户端？它看起来像你只需要一种方法来的请求间维持数据的。

But do you really have to send the data to the client again? It looks like you just need a way to persist the data between requests.

在这种情况下，最好是伊莫使用sessions^(docs).这也更安全的，因为否则客户端可以修改数据

In this case, it is better imo to use sessions^(docs). This is also more secure as otherwise the client could modify the data.
