Unfortunately (or fortunately?) split() function became deprecated as of PHP 5.3.0.

However besides annoying warning Deprecated: Function split() is deprecated in… it also means that soon this function is going to be completely unavailable. So it’s better not to wait when the warning turns into the fatal error.

Recommended alternative preg_split() has the same parameters, i.e. the only change required is just adding prefix preg_ to each call of split().

Of course if regular expression is not required then it is better apply explode() to split a string by string.
