404 error - Undefined index: REDIRECT_URL

Question

I don't understand. I set the 404 error in my .htaccess and it is redirected to error.php when I type something like http://{localhost}/mywebiste/xxx/xxx/xxx/xxx/

But I get this error,

Notice: Undefined index: REDIRECT_URL in C:\... 
Notice: Undefined index: REDIRECT_STATUS in C:\...

for,

$_SERVER["REDIRECT_URL"];
$_SERVER['REDIRECT_STATUS'];

.htaccess,

RewriteEngine on
ErrorDocument 404 http://{localhost}/projects/.../error.php

error.php,

$redirect_url = $_SERVER["REDIRECT_URL"];
$status = $_SERVER['REDIRECT_STATUS'];

Any ideas?

I have tried the codes from these two sites and none of them work,

1 2

Also, I'm on EasyPHP Devsever. I want to check whether there are

print_r($_SERVER);

I get this,

)

But I don't see REDIRECT_* as in the list here.

Any ideas how I can get REDIRECT_* working in my localhost?

Answer 1

You can avoid using full http:// in ErrorDocument 404 directive to get both values populated like this:

ErrorDocument 404 /projects/full/path/to/error.php

With this you will see both these values populated:

$_SERVER["REDIRECT_URL"]; // /mywebiste/xxx/xxx/xxx/xxx/
$_SERVER['REDIRECT_STATUS']; // 404
