예제

Example #1 Memcached::getServerByKey() example


<?php
$m = new Memcached();
$m->addServers(array(
    array('mem1.domain.com', 11211, 40),
    array('mem2.domain.com', 11211, 40),
    array('mem3.domain.com', 11211, 20),
));

$m->setOption(Memcached::OPT_LIBKETAMA_COMPATIBLE, true);

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

위 예제의 출력 예시:

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)
}
