How do I...remove filename extensions

[s_shrum]

I'm looking in my PHP book and see nothing about doing searchs from the end of a string.

Bear in mind that I could have filenames like:

foo.bar.doc

So doing forward searchs for the first occurance of '.' is not going to work.

I want to be able to extract the base name and the extension. The extension will be everything after the last period (at least in my cases it will be).

I use the following script to break apart the name of an uploaded file and add in today's date before putting it back together.

//get todays date
$today = gmdate ("Y-m-d", mktime (1,1,1998));

//get length of filename to use when we need to break it apart
$filename_length = strlen ($file_name);

//extract the file extension, this does not include the fullstop
$ext = substr (strrchr ($file_name, "."), 1);

//find position of last fullstop, ie, the one before the file extension
$last_fullstop_position = strrpos ($file_name, ".");

//break apart the filename to remove the extension
$filename = substr ($userfile_name, 0, $fullstop_position);

//replace spaces with underscore
$filename[$i] = eregi_replace(" ",  "_", $filename[$i]);

//add date and extension to filename	
$filename[$i]= $filename[$i]."($today).$ext";

That worked perfectly (with some minor modifications).
