how to display filename in php?

let's say my filename is like
http://www.xxx.com/abc.php

Is the a way to display the filename on the page and without the file type?

Like i'll be displaying the text like:
Buy abc online

I've searched everywhere but no luck .. i've several hundreds on page to be done so i dont think i can handcode them one by one ..

 

$PHP_SELF and trim the extension off with substr()?

 

sorry im a php noob. I know very very little of php ..
Can you show me how to do that?

with echo?

 

I've finally got it :

<?php $rest = substr(getenv('SCRIPT_NAME'), 1, -4);
echo $rest;?>

i feel good as im a php noob. I combined a few examples out there
