because the question was "I want to replace the extension '.cfm' with '-meta.cfm',
which I assumed meant the OP didn't want 'my.cfm.php' to become 'my-meta.cfm.php'
and a str_replace('.cfm', '-meta.cfm', $foo) would not be correct in that situation.

hopefully now the use of preg_replace() in my example makes sense.

oh and I forget to add delimeters to the regexps in my examples, which was a stupid
oversight.
