Examples
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'));
?>
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)
}
