php memcached客户端 - 设置数据时不起作用

Question

我正在尝试php memcached客户端。看来，默认情况下，在PHP模因中进行设置操作。我尝试设置一个中等大的字符串数据，当我在telnet中运行get命令时，我获得的值仅以纯文本为单位。现在，当使用memcache完成相同的情况时，值是乱/难以辨认的。这不仅是我检查了Telnet中的统计数据。这是结果

memcache - compressed
bytes - 148
memcache - uncompressed
bytes - 285
memcached - uncompressed
bytes - 285
memcached - uncompressed
bytes - 285

您可以看到，使用PHP memcache使我的压缩为50％。因此，压缩确实有效。但是使用PHP备忘录，我没有压缩。即使我使用：

明确打开压缩，这也是如此

$objMemcached->setOption(Memcached::OPT_COMPRESSION, true);  //default fastlz compression
OR
$objMemcached->setOption(Memcached::OPT_COMPRESSION, true);
$objMemcached->setOption(Memcached::OPT_COMPRESSION_TYPE, Memcached::COMPRESSION_ZLIB );

我是否需要设置其他选项才能使此工作？自3周以来，我就从事这个项目了，如果压缩不起作用，我的老板将不接受从Memcache到Memcached的迁移。我希望您了解紧迫性;）（Kiddnig）。

版本：

memcached     - 1.4.5
php-memcached - 2.0.1
libmemcached  - 1.0.8

请帮助。

Answer 1

尝试设置memcached.compression_threshold in php.ini

memcached.compression_threshold = 100

然后设置值并使用telnet进行检查。

您的memcached.ini for参考

memcached.ini

; Enable PECL memcached extension module
