If I am writing my own code correctly, $_SERVER['PHP_SELF'] should
return the full path of the script and filename from the document root
of the website. If your host has your subdomain set up right, you
should be able to issue: "echo
$_SERVER['DOCUMENT_ROOT'].$_SERVER['PHP_SELF']" in a php script and have
it return the complete path of the file via the filesystem... take out
the "DOCUMENT_ROOT" and you should be left with the path the webserver
uses to the script. The above example is what I use to include files
not in the same directory, minus the php_self obviously.
However, in cases where I submit a form back onto itself I use
$_SERVER['PHP_SELF'] all the time. Hence my questioning if you know
what the server is using for DOCUMENT_ROOT. If it thinks the document
root is "/var/www/domain.com/" and the PHP_SELF refers to
"/sub/form.php", then php_self will not return what you expect, nor want
it to.
I would suggest taking a look at:
http://us3.php.net/reserved.variables for more help.
Hope that helps,
Tony
