$_SERVER['SCRIPT_NAME'] issue

Question

I'm currently learning PHP and from what I'm seeing $_SERVER ['SCRIPT_NAME']; contains the current script's path. However, any page I try to identify shows up as "/index.php".

For example, I will run this on about.php, but the results return "/index.php".

<?php
    $current_file = $_SERVER['SCRIPT_NAME'];
    echo $current_file;
?>

Obviously I'm missing something, but I don't see what it is.

Yes, you are missing something, but I can't tell what from your information. Of course it always shows the called script, that is the name given in the URL. — Str.

Since your about.php is a template file that is at some point included in index.php, that is why you are getting /index.php as a result.

You should try using __FILE__:

The full path and filename of the file. If used inside an include, the name of the included file is returned. Since PHP 4.0.2, __FILE__ always contains an absolute path with symlinks resolved whereas in older versions it contained relative path under some circumstances.

Thanks for your response, decker. The reason I am using is to have a form direct back to the page it was on once completed. <form action="$current_file" method="POST"> with $current_file = (__FILE__) returns a url of the full path. Is there another way to return the user back to the original page without using the actual url? NOTE: This is for a login form, so I am giving users access to login on any page.

you could try action="<?=($_SERVER['PHP_SELF'])?>" or action="?" for the form's action attribute. Also, action="" works but I don't think it is valid HTML5.

Thanks, no action necessary (I did not know that). However, that did initially give me an issue - without the action, after signing in I had to refresh the page to get rid of the form. I simply did a header redirect to the referrer page upon complete and viola! Thanks again!

'SCRIPT_NAME' Contains the current script's path. This is useful for pages which need to point to themselves. The __FILE__ constant contains the full path and filename of the current (i.e. included) file.

Excerpt from http://www.php.net/manual/en/reserved.variables.server.php

The php.net website documentation is very verbose with some excellent user comments. I would suggest that be your first stop for almost any question you have about php.

You may want PHP_SELF

'PHP_SELF' The filename of the currently executing script, relative to the document root. For instance, $_SERVER['PHP_SELF'] in a script at the address http://example.com/foo/bar.php would be /foo/bar.php. The __FILE__ constant contains the full path and filename of the current (i.e. included) file. If PHP is running as a command-line processor this variable contains the script name since PHP 4.3.0. Previously it was not available.

Thanks for your response. That's actually been the resource I've been using. I have tried PHP_SELF but still get the same results
