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/
