Absolutely. Any time you need a list of files that can be specified by a 
wildcard expression, glob() is by far my favorite. Another neat trick with 
glob() is to check out the options regarding braces. They'll enable you to 
put in globs that are even more specific:

Find the right apache logs:
glob("/var/log/httpd-{access,error}.log") =
/var/log/httpd-access.log (if it exists)
/var/log/httpd-error.log (if it exists)

Find some images of certain extensions:
glob("*.{png,jpg,gif}")

Or find all your executable files in the normal directories:
glob("{,/usr{,/local}}/{,s}bin/*")
/bin/*
/usr/bin/*
/usr/local/bin/*
/sbin/*
/usr/sbin/*
/usr/local/sbin/*

There's so much that glob can do that opendir/readdir/closedir just can't 
even touch. And if glob doesn't do what you need, use backticks to run a 
"find" command in the shell with all the right parameters, and you can't 
go wrong.
