Question

The PHP manual for split() says

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly dis

Answer 1

It's been deprecated because

• explode() is substantially faster because it doesn't split based on a regular expression, so the string doesn't have to be analyzed by the regex parser
• preg_split() is faster and uses PCRE regular expressions for regex splits

join() and implode() are aliases of each other and therefore don't have any differences.
