你如何在PHP中使用memcache

Question

我终于在家用电脑上运行了memcache,所以我终于可以开始使用它了!

虽然我正在尝试使用代码,但我没有一个好的开始

php.net @memcache-set 我无法获得他们发布的示例代码

我试过这个:

<?php
/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
memcache_set($memcache_obj, 'var_key', 'some variable', 0, 30);
echo memcache_get($memcache_obj, 'var_key');
?>

---

然后

<?php
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$memcache_obj->set('var_key', 'some really big variable', MEMCACHE_COMPRESSED, 50);
echo $memcache_obj->get('var_key');
?>

---

并从上面的代码中得到了这些错误;

Warning: Memcache::connect() [memcache.connect]: Can't connect to memcache_host:11211, A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (10060) in C:\webserver\htdocs\test\memcache\index.php on line 36

Warning: Memcache::set() [memcache.set]: Failed to extract 'connection' variable from object in C:\webserver\htdocs\test\memcache\index.php on line 42

Warning: Memcache::get() [memcache.get]: Failed to extract 'connection' variable from object in C:\webserver\htdocs\test\memcache\index.php on line 44

然后我在网上找到了这个代码,它确实有效

<?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");

$tmp_object = new stdClass;
$tmp_object->str_attr = 'test';
$tmp_object->int_attr = 123;
// add cache
$memcache->set('key', $tmp_object, false, 30) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 30 seconds)<br/>\n";
// get cache
$get_result = $memcache->get('key');
echo "Data from the cache:<br/>\n";
var_dump($get_result);
?>

我怎样才能从PHP.net中获取示例？

此外,我很想看到任何涉及memcache的emample代码,你可能想要分享我真的很感激看到一些有用的例子

您是否意识到需要将"memcache_host"替换为您的主机名和/或localhost？还是我完全忽略了这一点？此外,尝试telnet localhost 11211然后telnet your-memcache-host-name 11211看看你是否得到相同的结果(你应该).
