Memcache::setCompressThreshold开启大值自动压缩

说明

bool Memcache::setCompressThreshold ( int $threshold [, float $min_savings ] )

Memcache::setCompressThreshold()开启对于大值的自动压缩。 同样你也可以使用函数memcache_set_compress_threshold()

Note:

此函数在memcache2.0.0加入。

参数

threshold

控制多大值进行自动压缩的阈值。

min_saving

指定经过压缩实际存储的值的压缩率,支持的值必须在0和1之间。默认值是0.2表示20%压缩率。

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE

范例

Example #1 Memcache::setCompressThreshold() 示例

<?php

/* OO API */

$memcache_obj = new Memcache;
$memcache_obj->addServer('memcache_host'11211);
$memcache_obj->setCompressThreshold(200000.2);

/* procedural API */

$memcache_obj memcache_connect('memcache_host'11211);
memcache_set_compress_threshold($memcache_obj200000.2);

The strangest thing is that you don't supply a server as parameter to setCompressThreshold(), so the value should be related to the memcache module, not the server itself. However it's required that you have added a server before you can set compress threshold.  The documentation does not specify if  the servers that are added after the call to this function will have the set value. I would test it and post, but  since it's not documented the behavior could change.
So if you want to be sure -> set the threshold every time you add a server.
