Memcached::getDelayed
(PECL memcached >= 0.1.0)
Memcached::getDelayed — Request multiple items
Description
Memcached::getDelayed() issues a request to memcache for
multiple items the keys of which are specified in the
keys
array. The method does not wait for response
and returns right away. When you are ready to collect the items, call
either Memcached::fetch() or
Memcached::fetchAll(). If with_cas
is true, the CAS token values will also be requested.
Instead of fetching the results explicitly, you can specify a result callback via
value_cb
parameter.
Parameters
-
keys
-
Array of keys to request.
-
with_cas
-
Whether to request CAS token values also.
-
value_cb
-
The result callback or
null
.
Return Values
Returns true
on success or false
on failure.
Use Memcached::getResultCode() if necessary.
Examples
Example #1 Memcached::getDelayed() example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
$m->set('int', 99);
$m->set('string', 'a simple string');
$m->set('array', array(11, 12));
$m->getDelayed(array('int', 'array'), true);
var_dump($m->fetchAll());
?>
The above example will output:
array(2) { [0]=> array(3) { ["key"]=> string(3) "int" ["value"]=> int(99) ["cas"]=> float(2363) } [1]=> array(3) { ["key"]=> string(5) "array" ["value"]=> array(2) { [0]=> int(11) [1]=> int(12) } ["cas"]=> float(2365) } }
