php8.2-apcu 5.1.22+4.0.11-2build1 (riscv64 binary) in ubuntu mantic

 The APCu is userland caching: APC (Alternative PHP Cache) stripped of
 opcode caching after the deployment of Zend OpCache in PHP 5.5 as the
 primary solution to opcode caching in future versions of PHP.
 .
 The APCu is a fast solution for userland caching (and dumping) of PHP
 variables locally, it is not distributed like MemcacheD, but they can
 be used together for optimal caching.
