PHP already does ALL that for you. You just need to save the file to
your DB. See the $_FILES global array for uploaded files.
Cheers,

PHP already does ALL that for you. You just need to save the file to

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";
Anything would be helpful. :)
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?

Eventually, I wind up with a query similar to:
UPDATE table_01 SET field_a = 'New value here', updated=CURDATE() WHERE
primary_key=12345
Even though you've solved it one way to work out the problem here would
be to change it to a select query (unfortunately mysql can't explain
insert/update/delete statements - which would make it a lot easier).
ie change it to
select 1 from table where primary_key=12345;
If that's slow, then you're missing an index on primary_key.
If that's fast.. err, you're back to square one :/ or maybe you have too
many indexes (which means the update process is spending all of it's
time updating the fields & indexes).
