regular expression and forward slash
i'm searching for keywords in a string via a regular expression. It works fine for all keywords, exept one which contains a forward slash in it: "time/emit" .
Even using preg_quote($find,'/'), which escapes it, i still get the message:
Unknown modifier 't' in /frontend.functions.php on line 71
If i print the find pattern, it shows /time\/emit/ . Without preg_quote, it shows /time/emit/ and both return the same error message.
Any bit of knowledge would be useful.

Try to begin and end your regular expression with different sign than /
I personally use `
I've seen people using #
I think most chars are good. You can read more about it here: http://pl.php.net/manual/en/regexp.reference.delimiters.php
Like this:
preg_match('#time/emit#', $subject); // instead of /time/emit/
To put it another way: Your $find variable should contain rather #time/emit# than /time/emit/

looks like you have something already escaping it..
preg_quote('time/emit') // returns time/emit
preg_quote('time/emit') // returns time\/emit
as a hack you could simply do:
preg_quote(stripslashes($find)) // will return time/emit
