memcached密钥
问题描述：
Is it possible?
$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");
}
是否可以？ p>
$ mc = new Memcached（ ）;
$ mc-＆gt; addServer（“127.0.0.1”，11211）;
$ data = array（
'key_one'=＆gt; array（'something'=＆gt;'0'，\ n'thing_else1'=＆gt; 1，
'thing_else2'=＆gt; 2，
'something_else3'=＆gt; 3，
），
'key_two'=＆gt; array（'something'=＆gt; ;'0'，
'something_else1'=＆gt; 1，
'something_else2'=＆gt; 2，
'something_else3'=＆gt; 3，
）
）;
$ result = $ mc- ＆gt; get（“data ['key_one'] ['something_else2']”）;
if（$ result）{
echo $ result;
} else {
echo“没有关于缓存的数据。请刷新页面按 F5“;
$ mc-＆gt; set（”data“，$ data，15）或die（”无法在Memcached服务器上保存数据“）;
}

答
Your set() should work:
$mc->set('data', $data, 15);
And to get():
$result = $mc->get('data');
$something = $result['key_one']['something_else2'];
//or PHP >= 5.4.0
$result = $mc->get('data')['key_one']['something_else2'];
答
No, will not work. Memcached is a Key-Value store. So you can retrieve the data stored by a unique key. What will work is:
$_temp_result = $mc->get('key_one');
$result = $_temp_result['something_else2']
Assuming the data is stored in Memcached as shown in $data

Hmm okey but how about set multi, wich could be correct?
$mc->set('data')['key_deeper_1'],$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'];
