Example #1 Memcached::getServerByKey() example

<?php
$m 
= new Memcached();
$m->addServers(array(
    array(
'mem1.domain.com'1121140),
    array(
'mem2.domain.com'1121140),
    array(
'mem3.domain.com'1121120),
));

$m->setOption(Memcached::OPT_LIBKETAMA_COMPATIBLEtrue);

var_dump($m->getServerByKey('user'));
var_dump($m->getServerByKey('log'));
var_dump($m->getServerByKey('ip'));
?>

The above example will output something similar to:

 array(3) { ["host"]=> string(15) "mem3.domain.com" ["port"]=> int(11211) ["weight"]=> int(20) } array(3) { ["host"]=> string(15) "mem2.domain.com" ["port"]=> int(11211) ["weight"]=> int(40) } array(3) { ["host"]=> string(15) "mem2.domain.com" ["port"]=> int(11211) ["weight"]=> int(40) }
