memcached密钥

Question

有可能吗？

$mc = new Memcached();
$mc->addServer("127.0.0.1", 11211);
$data = array(

         'key_one' => array('something' => '0',
                          'something_else1' => 1,
                          'something_else2' => 2,
                          'something_else3' => 3,
                         ),

          'key_two' =>   array('something' => '0',
                         'something_else1' => 1,
                         'something_else2' => 2,
                         'something_else3' => 3,
                         )
         );
$result = $mc->get("data['key_one']['something_else2']");
if($result) {
  echo $result;
} else {
  echo "No data on Cache. Please refresh page pressing F5";
  $mc->set("data", $data,15) or die ("Failed to save data at Memcached server");
}

Answer 1

您的set()应该有效：

$mc->set('data', $data, 15);

到get()：

$result = $mc->get('data');
$something = $result['key_one']['something_else2'];
//or PHP >= 5.4.0
$result = $mc->get('data')['key_one']['something_else2'];

Answer 2

不，不行。 Memcached是一个Key-Value商店。因此，您可以检索由唯一键存储的数据。 将起作用的是：

$_temp_result = $mc->get('key_one');
$result = $_temp_result['something_else2']

假设数据存储在Memcached中，如$data

Answer 3

嗯，但是如何设置多个，这可能是正确的？

$mc->set('data')['key_deeper_1'],$value, $expired_time);

or

$data = array('key_1' => array(
                                  'key_deeper_1' => 'value',
                                  'key_deeper_2' => 'value',

                              )
             );

$mc->set('data',$value, $expired_time);
$mc-> get('data')['key_deeper_1'];
