Subject: [PATCH] Fix null argument to preg_split
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deprecated Functionality: preg_split(): Passing null to parameter #3 ($limit) of type int is deprecated

https://www.php.net/manual/en/function.preg-split.php#refsect1-function.preg-split-parameters

limit:

If specified, then only substrings up to limit are returned with the
rest of the string being placed in the last substring. A limit of -1 or
0 means "no limit".
