 |
|
I'm trying to use %{REQUEST_URI} and %{QUERY_STRING} to redirect to a new url. For example, I start with this:
| Code: | | https://www.example.com/foo/?bar=1&lorem=2&ipsum=3 |
and I'm trying to redirect to this:
| Code: | | https://www.example.com/redirect.php?uri=/foo/&qs=bar%3D1%26lorem%3D2%26ipsum%3D3 |
I can be pretty flexible, but in redirect.php I just need to end up with a variable that looks like:
| Code: | | $uri = 'https://www.new.com/foo/?bar=1&lorem=2&ipsum=3' |
I started out just using [QSA], but since I don't know the variables that'll be sent I ended up with a PHP script that is unnecessarily complex:
| Code: | // starting with this:
// https://www.example.com/redirect.php?uri=/foo/&bar=1&lorem=2&ipsum=3
$uri = 'https://www.new.com' . $_GET['uri'];
unset($_GET['uri']);
if (!empty($_GET)) {
$uri .= '?';
foreach ($_GET as $key => $val)
$uri .= $key . '=' . $val . '&';
} |
Is there a way that I can URL encode %{QUERY_STRING}? If so, I could eliminate all of that and just use:
| Code: | // I know this could leave a trailing ? if
// there's no query string, but that's OK
$uri = 'https://www.new.com' . ($_GET['uri'] ?? false) . '?' . urldecode($_GET['qs'] ?? false); |

use $_SERVER array.
'QUERY_STRING' and 'REQUEST_URI'.
Also take a look at the filter_input() function. |
