What should I do if there is an error in php split?

PHP's split() is very convenient, but after PHP530, it is not recommended to continue to use split(), and a warning message will appear during use.

split() is not recommended Reason

For regex after PHP 5.3.0, if you want to use PCRE specifications, POSIXReaex is not recommended to be used (unify Reaex to avoid too many specifications?)

So the following is not recommended Function(POSIXL, and a list of Function(PCRE) recommended for replacement, see: PHP; Differences from POSIX regex

POSIX-PCRE
ereg_replace()→preg_replace() ereg()→preg_match()
eregi_replace()→preg_replace() eregi()→preg_match() split()→preg_split() spliti()→preg_split()
sql_regcase()→No equivalent

PHPsplit() alternative

Requires regex split, preg_split can be used () instead

No need for reaex. As long as you want to quickly split a fixed string, you can use explode() instead (the speed will be much faster than that which requires reaex)
