Pass Data from One PHP Page to Another using header()
提问by user1059869
I want to send data from one PHP file to another PHP file in a subfolder where the first PHP file is present. I have a folder named folder1which has contains a PHP file named file1.phpand I want to call another file named file2.phpin a subfolder of folder1named folder2. I am using the header()function like this in file1.php:
我想将数据从一个 PHP 文件发送到存在第一个 PHP 文件的子文件夹中的另一个 PHP 文件。我有一个名为的文件夹folder1，其中包含一个名为的 PHP 文件file1.php，我想调用file2.php在named的子文件夹中folder1命名的另一个文件folder2。我正在使用这样的header()功能file1.php：
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim(dirname($_SERVER['PHP_SELF']), '/\');
$extra = 'folder1/folder2/file2.php';
header("location:http://$host$uri/$extra?sms=".$msg."&num=".$msg_num);
Data is not passing. Is there any solution using header()? I can't use cURLbecause of some restrictions.
数据不通过。有什么解决方案header()吗？cURL由于某些限制，我无法使用。

The following code works:
以下代码有效：
file1.php:
file1.php：
<?php
header( 'Location: inner/file2.php?x=1&y=2&z=3' );
?>
inner/file2.php:
inner/file2.php：
<?php
print '<pre>';
var_dump( $_GET );
print '</pre>';
?>
The result of visiting http://localhost/testing/file1.phpis a redirect to http://localhost/testing/inner/file2.php?x=1&y=2&z=3which displays:
访问的结果http://localhost/testing/file1.php是重定向到http://localhost/testing/inner/file2.php?x=1&y=2&z=3，显示：
array(3) {
["x"]=>
string(1) "1"
["y"]=>
string(1) "2"
["z"]=>
string(1) "3"
}
I would suggest copying over these test files and proving to yourself that the basic concept of redirecting with passed values is working. Then, build up the rest of your code around a known-good kernel. Good luck!
我建议复制这些测试文件并向自己证明使用传递值重定向的基本概念是有效的。然后，围绕已知良好的内核构建其余代码。祝你好运！

Without an example of the variables you want to send, it's kind of hard to tell what the problem might be, but a possible problem could be the characters in the variables.
如果没有您要发送的变量示例，则很难判断可能是什么问题，但可能的问题可能是变量中的字符。
To make sure there are no invalid characters, you can use urlencode(), perhaps in combination with htmlentities(), see the manual:
为确保没有无效字符，您可以使用urlencode()，也许与 结合使用htmlentities()，请参阅手册：
header("location:http://$host$uri/$extra?sms=".urlencode($msg)."&num=".urlencode($msg_num));
