i got 1 simple question: kind of data structure stack? static or dynamic data structure? looking answer , couldn't find it, therefore got own "explanation" - guess, when can implement either using array or linked list, can be... both?, depending on implementation? reasoning make sense? by definition, static data structure has fixed size. if can limit size of stack pre-determined number, stack becomes static data structure. size size of storage, plus size of stack pointer or stack index indicating current location. a stack of unlimited capacity dynamic data structure, regardless of implementation. implemented linked list or array re-allocate upon reaching capacity, size of such stack changes add or remove data.

i'm using zend_shm_cache functions fast storage of variables. problem cache doesn't seem cleared after ttl over. example: zend_shm_cache_store( $key = 'test3', 'value', 2 ); foreach( range(1,5) $timer ){ sleep( 1 ); echo $timer.' - ' .zend_shm_cache_fetch( $key ).'<br/>'; } returns: 1 - value 2 - 3 - value 4 - value 5 - value i expect cache empty after second second. can explain what's happening or propose solution? i got answer in documentation of apcu: after ttl has passed, stored variable expunged cache (on next request). as code runs in 1 request cache never deleted when time has expired.
