Result callbacks

Result callbacks are invoked by Memcached::getDelayed() or Memcached::getDelayedBykey() methods for each item in the result set. The callback is passed the Memcached object and the array with the item information. The callback does not have to return anything.

Example #1 Result callback example


<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
$items = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
);
$m->setMulti($items);
$m->getDelayed(array('key1', 'key3'), true, 'result_cb');

function result_cb($memc, $item)
{
    var_dump($item);
}
?>
