I run two Apache 2 servers. One has PHP5.2 and the other has PHP5.3. Is there a reason why on the 5.3 machine has $_SERVER['SCRIPT_URI']?
Where does this variable come from? It is clearly something that is coming through from the Apache environment and it is not documented in the PHP manual. It is however a handy shortcut over a combination of ['HTTPS'], ['SERVER_NAME'] and ['REQUEST_URI'].
I have tried looking through configuration files, searching SO and the web.
According to a post on WebHostingTalk it comes from mod_rewrite:
Add
RewriteEngine OnTo the virtual host in your httpd.conf file that you want to turn this on for and then restart apache.
I moved to CentOS 7 with Plesk12, PHP 5.6.6 and rewrite on etc. SCRIPT_URI has not been there. And because it is so nice to use in some situations I wrote this workaround:
if(!isset($_SERVER['SCRIPT_URI'])){
$_SERVER['SCRIPT_URI'] = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on' ? 'https://' : 'http://').$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$pos = strrpos($_SERVER['SCRIPT_URI'],'/');
if($pos!==false) {
$_SERVER['SCRIPT_URI'] = substr($_SERVER['SCRIPT_URI'], 0, $pos+1);
}
}
As I am not a total expert, please review this code to your specific application before plugging it in. On my system it seems to work perfectly. I just put it in the Head-Area of my index.php and others.
As far as I know $_SERVER['SCRIPT_URI'] is only available if you're running PHP as a CGI. I suppose that must be the difference in your two PHP installations.
