PHP

• Better memory handling when getting near the shared memory limit.

• user-level access to store PHP variables in shared memory easily.

• Quick way to load constants from shared memory

apc_store/fetch


<?php
  $a = array(1,2,3);
  apc_store('my_array', $a, 5);
  $a = 0;
  echo "<pre>"; var_dump($a); echo "</pre>";
  $b = apc_fetch('my_array');
  echo "<pre>"; var_dump($b); echo "</pre>";
?>

int(0)

array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
}

save/load constants


<?php
  if(!apc_load_constants('my_constants')) {
    $constants = array('ABC'=>'testing',
                       'DEF'=>123,
                       'FOO'=>'Bar');
    apc_define_constants('my_constants', $constants);
  }
