PHP Memcached存储数组，检索对象.一只虫子

使用MemcacheD v1.4.22

PECL MemcacheD库v2.2.0

PHP v.3.19（cli）

我正在尝试将数组存储到缓存中

$array = $sql->get_arr ('SELECT properties FROM obj_properties WHERE obj_id="'.$id.'"');
var_dump($array); // output below
array(10) {
  [0]           => string(3) "976"
  ["parent"]    => string(3) "976"
  [1]           => string(5) "Ziedi"
  ["name"]      => string(5) "Ziedi"
  [2]           => string(0) ""
  ["int_name"]  => string(0) ""
  [3]           => string(1) "1"
  ["type"]      => string(1) "1"
  [4]           => string(1) "1"
  ["status"]    => string(1) "1"
}
$memcached->set( $memKey, $ret_val, $max_time );
$returnArray = $memcached->get( $memKey );
var_dump($returnArray); // output below
object(stdClass)#5 (10) {
  ["0"]         => string(3) "976"
  ["parent"]    => string(3) "976"
  ["1"]         => string(5) "Ziedi"
  ["name"]      => string(5) "Ziedi"
  ["2"]         => string(0) ""
  ["int_name"]  => string(0) ""
  ["3"]         => string(1) "1"
  ["type"]      => string(1) "1"
  ["4"]         => string(1) "1"
  ["status"]    => string(1) "1"
}

我正在存储一个带有混合整数/字符串键的数组，这对php来说应该不是问题，但显然对memcached来说是问题？有记录吗？有什么变通方法或提示吗？

如果我看一下终端输出的密钥：

$ telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
get dev_id_1_04115ec378e476c56d19d827bcf8db56
VALUE dev_id_1_04115ec378e476c56d19d827bcf8db56 6 114
{"0":"976","parent":"976","1":"Ziedi","name":"Ziedi","2":"","int_name":"","3":"1","type":"1","4":"1","status":"1"}

我们看到数组实际上被保存为对象，而不是数组，这意味着输出是正确的，但存储以某种方式将此数组转换为对象。。。

不幸的是，我无法摆脱基于字符串或int的数组键元素，所以我将不得不以某种方式处理它们。

感谢您的帮助。
