included file being self-aware???

[shadedecho]

ok, simple enough (or at least it sounds that way) question:


blah.php:

<?php

echo &quot;blah<br>\n&quot;;

include(&quot;blah.inc&quot;);

?>

blah.inc:

<?php

echo $PHP_SELF;

?>

this produces:

blah
blah.php

I want to know how the include file can be "self-aware" such that it knows its own filename, like "blah.inc" or whatever... is there a way to do this?

the output would then be:

blah
blah.inc

Thanks!

$PHPSELF is the script invoked by the web server.

basename(__FILE__)

will give you the name of the file PHP is currently running.

basename() :

__FILE__ :

I thought it was $PHP_SELF (With the underscore)
That's the way I've always seen it used.

And also, everytime I tried using a script with a variable PHP_SELF (or whichever way is correct), it always tells me the PHP_SELF variable is undefined and the whole script won't work.

Any idea what causes this?

thanks, that's exactly what I needed!

btw, in versions of PHP prior to 4.0.6, __FILE__ apparently does not give the absolute path, just the filename (making there be no need for basename() in this case).

depending on what version of PHP you are running, you may need to refer to that variable as

$HTTP_SERVER_VARS['PHP_SELF']

I'm using version 4.3.1

I'll check into that suggestion later tonight when I get the chance. Thanks!

It really all depends on the setting of register_globals in php.ini.

If it's set to "off", then you must, as shadedech has said, reference the variable as $HTTP_SERVER_VARS['PHP_SELF'] or (for newer versions fo PHP) $_SERVER['PHP_SELF'].

Setting it to "on" should enable you to reference it as $PHP_SELF. But I and the online manual recommend (

http://www.php.net/manual/en/security.registerglobals.php)leaving

register_globals set to "off".

In older versions of PHP, the default setting for register_globals was "on". In newer versions, the default is "off". If you are looking at older script examples, they will commonly reference $PHP_SELF, expecting it so be available. Want the best answers? Ask the best questions:
