If you end up in a situation where your PHP installation gets ahead of your application (like fx. if your hosting provider deprecates PHP 7.4 without you having had the opportunity to update your WordPress 4.9.22 blog), here is a small tip if this results in errors related to the, in PHP 8 removed, function get_magic_quotes_gpc() (see PHP RFC from 2018 about this decision).
As this function has been a dummy function returning false since PHP 5.4 (see php-src commit removing the functionality) and emitting a deprecation warning since PHP 7.4 (see php-src commit deprecating function) in almost any case perceivable you would be able to fake this function and satisfy your application’s need for it to exist.
To fix this for WordPress add the following line to the wp-includes/load.php file (fx. at line 7 for v4.9.22);
function get_magic_quotes_gpc() {return false;}
And voila! WordPress will be functional again (please consider using the chance to upgrade).
Unless, of course, there are other problems related to the PHP upgrade…
This could fx. be ancient themes (like Ahimsa) that use deprecated associative array notation (unquoted string literal indexes). These needs fixing first by adding quotes to all of the indexing strings in sub-arrays of the $skin_fields array, like below;
