Memcached::getResultMessage
The parameter server_key is very confusing, it's not a server key for MemCached Server, but it's key,in key-value pair which you stored in server.
<?php
$m = new Memcached;
$m->addServers(array(
array('127.0.0.1',11212),
array('127.0.0.1',11211)
));
for($i=0;$i<10;$i++){
$key = 'key_'.$i;
$m->add($key, 1);
}
for($i=0;$i<10;$i++) {
$key = 'key_'.$i;
$arr = $m->getServerByKey($key);
echo ($key.":\t".$arr['port']."\n");
}
?>
key_0: 11212
key_1: 11211
key_2: 11212
key_3: 11212
key_4: 11212
key_5: 11211
key_6: 11211
key_7: 11212
key_8: 11212
key_9: 11211
Memcached::getServerByKey
(PECL memcached >= 0.1.0)
Memcached::getServerByKey — Map a key to a server
Description
public array Memcached::getServerByKey
( string $server_key
)
Memcached::getServerByKey() returns the server that would be selected by a particular server_key in all the Memcached::*ByKey() operations.
Parameters
- server_key
-
The key identifying the server to store the value on.
Return Values
Returns TRUE on success or FALSE on failure. Use Memcached::getResultCode() if necessary.
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)
}
