PHP Memcached 存储数组，检索对象。错误？

Question

使用 MemcacheD v1.4.22

PECL MemcacheD 库 v2.2.0

PHP v5.3.19 (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"
}

我正在存储一个包含混合 integer/string 键的数组，这对 php 应该不是问题，但显然它是针对 memcached 的？它记录在任何地方吗？任何解决方法或提示？

如果我查看密钥的终端输出：

$ 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，但不知何故存储将该数组转换为对象...

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

感谢任何帮助。

经过两天的痛苦研究后发现，memcached 配置被设置为序列化到 php.ini 文件中的对象：

memcached.serializer = "json"

改为

memcached.serializer = "json_array"
