What is the difference between split() and explode()?

Split() function has 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. Simply it splits string.
• 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.
