grabing filename from web address..

crawfd

If I have the web address:

http://mysite/images/screenshot1/weddingnature.jpg

how do grap the weddingnature.jpg filename. Actually I'm looking to just get the extension for use in a if/else statement.

I tried using


<? 

$fullurl = $_SERVER["HTTP_REFERER"];

echo "$fullurl";


?>

But that doesn't work because it's trying to I suppose retrieve the previous referrer address. I'd like to take the web address at the page I'm currently on. Is that possible?

Thanks

If you want the name of the page you are on, it is available in $_SERVER['PHP_SELF'].

Here's a link to an explanation of the $_SERVER array.

If you just want the filename of the current script, and not it's location or anything, you would probably use $_SERVER['SCRIPT_FILENAME'].

$_SERVER['SCRIPT_FILENAME'] will give you the absolute path to the file. eg
/usr/local/apache2/htdocs/sript.php

The only way I could see you being able to do it would be to use SCRIPT_FILENAME or PHP_SELF and then get rid of the other stuff in the variable and leave yourself with the script.php

...just get the extension...

$path_info = pathinfo($_SERVER['SCRIPT_FILENAME']);
$extension = $path_info['extension'];
