the $_SERVER['SERVER_PORT'] part should be changed to $_SERVER['HTTP_HOST']

The Environment variable $ENV is useful for coding portable platform specific application constants.

// Define a Windows or else Linux root directory path
$_ENV['OS'] == 'Windows_NT' ? $path = 'L:\\www\\' : $path = ' /var/www/';

define('PATH', $path);

echo PATH;

Sorry if this is old news to some, but it might not be obvious at a first glance:

If you are using $_SERVER['remote_addr'] as a way to keep track of a logged-in user (this can be useful to avoid several types of hacking), remember that it might not be the user's actual IP address!

I was trying to implement a login feature that used this, storing the IP into a DB. It went smoothly while on a LAN, but wrecked havoc when accepting outter connections.

you can use these to reconstructed the current page url.

<?php

echo 'http';
if($_SERVER['HTTPS']=='on'){echo 's';}
echo '://'.$_SERVER['SERVER_PORT'].$_SERVER['SCRIPT_NAME'];
if($_SERVER['QUERY_STRING']>' '){echo '?'.$_SERVER['QUERY_STRING'];}

?>

If $_SERVER['HTTPS']=='on' does not work for you,
try $_SERVER['SERVER_PORT']==443 (or whatever secure port is used)

Hi dotpointer,

I am new to php but I suggest a little modification of your script. Tell me what you think of it :

function getThisFile() {

[...]
    /* last resort __FILE__ */
    } else {
        $strScript = __FILE__;
    }
[...]
}

Thanks for this great function, I'll use it for my project !

Regards

If your having problems returning $_SERVER variables using apache, be sure you enable:

ExtendedStatus On

in your httpd.conf file.

If it's off, then things like $_SERVER['HTTP_HOST'] won't be present.

The variable $php_errormsg is not populated if you have XDebug running.

Driven crazy by the lack of consistency with $_SERVER across installations? Check out this chart:

if you are trying to use $php_errormsg, it acts more like a function than it does a variable.
