Comment:

 Hi @seanosh, thanks for opening a ticket.

 WordPress has been using `microtime()` to generate the last changed value
 for quite a while across several different cache keys.n 4.7, some of this
 has been combined into the new `wp_cache_get_last_changed()` function. See
 #37464.

 After some initial testing with memcached 1.4.2, PECL memcached, and PHP
 7.0.9 (thanks @johnjamesjacoby), it seems that memcached is able to store
 and retrieve the cache fine. It may just drop the piece after the space
 when storing the key.

 Can you provide the PHP and memcached versions you are using as well as
 the drop-in?
