    Description

    Memcache::setCompressThreshold(int $threshold, float $min_savings = ?): bool

    Memcache::setCompressThreshold() enables automatic compression of large values. You can also use the memcache_set_compress_threshold() function.

    Note:

    This function has been added to Memcache version 2.0.0.

    Parameters

    threshold

    Controls the minimum value length before attempting to compress automatically.

    min_saving

    Examples

    Example #1 Memcache::setCompressThreshold() example

    <?php

    /* OO API */

    $memcache_obj = new Memcache;
    $memcache_obj->addServer('memcache_host', 11211);
    $memcache_obj->setCompressThreshold(20000, 0.2);

    /* procedural API */

    $memcache_obj = memcache_connect('memcache_host', 11211);
    memcache_set_compress_threshold($memcache_obj, 20000, 0.2);

    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.
