"Magic quotes" were removed in PHP 5.4, no need to mitigate it anymore.
Avoid implode() with the join()-like order of arguments which was deprecated
since PHP 7.4 and implicitly since PHP 5.3.
Also avoid implode() with an implicit separator for stylistic reasons.
mktime() with no arguments has been deprecated since PHP 5.1.
