RE: RE: variable comparison

i like the substr approach myself, although i would make the small change of using the length function instead of hard coding the length of $ext.

if (substr($filename, -length($ext)) eq $ext)
{
    # do stuff
}
else
{
    # do other stuff
}

Agreed. I've been brainwashed by Redmond to assume that an
extension is three characters long. My early DOS training
is to blame for that. (good ol' 8.3 notation, you know?)

Using a regex to hunt for the dot is out of the question,
because you might have a filename "foo.bar.htm" for example.
Of course, you could always look for the last instance of
the . in the filename, but . . . in the interst of having
clearer code, I like the substr approach better than the
regex (if only this once ;-) )

for finding the last instance of a string in another string, you can use rindex.
