As of 5.5 and onward I replaced on my setups APC with APCu. APCu is APC without the opcode caching. It also provides the apc_
functions and passes checks for extension_loaded('apc')
.
Make sure you use at least v4.0.2 of this extension. Prior releases had a bug in which the apc_
functions were not available even when the APC compat mode was turned on.
