URL Parsing...

Hi,

I'm working on redesigning the backend of the website for work. It was
originally done in ColdFusion, but I'm switching it over to PHP - probably
going to transfer the website from where it's currently hosted to something
a lot cheaper, too, hence the switching to PHP. Anyway.

Because we are a manufacturing company, we have a few different lines of
products. Currently, each different product line has it's own page (and own
meta tags). The current set up has ColdFusion grabbing the current page
from the URL stripping off the '.cfm' extension and adding '-meta.cfm'
before including it in the header.

I'm sure there is a way to do this in PHP, but I'm out of shape enough with
using PHP that I can't remember, and I can't seem to find anything that will
work for me. I just want to be able to pull whatever address is in the URL,
get the file name, and go from there.

Any ideas?

Anything would be helpful. :)

Thanks,
Amanda

From what I've read recently about meta tags, why?

Most SE's have dropped their dependance on meta tags because of their abuse.

Cheers,

one of these should give you something to go on:

echo preg_replace('\.cfm$', '-meta.cfm', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)), "\n";
echo preg_replace('\.cfm$', '-meta.cfm', $_SERVER['PATH_TRANSLATED']), "\n";
echo preg_replace('\.cfm$', '-meta.cfm', $_SERVER['SCRIPT_FILENAME']), "\n";

You don't need the overhead of PCRE, though it is the fastest to write,
since it's already above for you...

Or parse_url(). basename(__FILE__) will get you the filename.

well if you take a string (filename) and wish to change the end of it somone
then I don't think str_replace() is the correct function. what's to say a script
doesn't exist called 'my.cfm.php'?

ah yes basename() - I forgot to put use that in the examples, good catch.

How does this:

/\.cfm$/

take into account that?

$ in regex's means 'end of string' - so it will only match .cfm at the
very end of the string.

Indeed, so how does the regex take into account ".cfm.php"? It doesn't.
If it doesn't have a .cfm extension, it won't match.

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.
