APC does not work for SuiteCRM 7.14, PHP8

[gunnicom]

Issue

The memory cache APC was available as APC-bc (backward compatibility) until PHP8 ( https://www.php.net/manual/de/apcu.installation.php )
After that only APCu is available. SuiteCRM exclusively uses apc functions (i.e. apc_store() ), but now has to use apcu_store() ...
As SuiteCRM 7.14.x is only compatible with PHP > 8 we can safely switch it to apcu, as noone could run apc anyway.

There is also someone in the forum in 2019 mentioning this ... as always, nothing got fixed https://community.suitecrm.com/t/apc-cache-not-working/69261
