Question

在第一页上，我有这个

// start memcached
$m = new Memcached();
$m->addServer('localhost', 11211);
$key = 'test_' . $ID_ref;
$test_data = array(....);
$m->set($key, $test_data);
// end memcached

好的，到目前为止。在下一页，

// start memcached
$m = new Memcached();
$m->connect('localhost', 11211);
var_dump($m->get($key));
// end memcached

发生以下错误：

调用未定义的方法Memcached :: connect（）

phpinfo()显示memcached是由webhost安装的，似乎是memcached does not support connect()

我应该使用什么？

而不是

<head>
  <style>
    popup {
      background-color: #eee;
      display: none;
      width: 300px;
      height: 400px;
      margin: 0 auto;
      border-style: solid;
      border-width: 2px;
    }
  </style>
</head>

      var a = myJ['a']
      var b = myJ['b']

      var r = myJ['RUNNING']

      table.innerHTML += "<tr><td><td>" + key + "</td><td>" + a + "</td><td>" + b + "</td><td>" + c + "</td><td>" + init + "</td><td>" + r + "</td><td><button onclick='openDialogue(" + key + ")'>Show Key</button></td></tr>"

    }
    return retTable

  function openDialogue(key) {

</script>

简单地重复使用

$m = new Memcached();
$m->connect('localhost', 11211);

$m = new Memcached(); $m->addServer('localhost', 11211);是一个 Memcache 方法而不是 Memcached
