使用header（）将数据从一个PHP页面传递到另一个PHP页面

Question

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 folder1 which has contains a PHP file named file1.php and I want to call another file named file2.php in a subfolder of folder1 named folder2. I am using the header() function like this in 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 cURL because of some restrictions.

Answer 1

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.

To make sure there are no invalid characters, you can use urlencode(), perhaps in combination with htmlentities(), see the manual:

header("location:http://$host$uri/$extra?sms=".urlencode($msg)."&num=".urlencode($msg_num));
