Memcached::get()could not unserialize value, no igbinary support

Question

使用laravel Cache::get()时报错，版本PHP7 ,报错文件
vendor/laravel/framework/src/Illuminate/Cache/MemcachedStore.php

已安装igbinary扩展

#php -m|grep igbinary
igbinary

更新,重新安装memcached,3.x版本是支持php7的，而php5.2-5.6需要使用2.x版本

$ wget https://codeload.github.com/php-memcached-dev/php-memcached/tar.gz/v3.1.3 
$   tar -zxvf php-memcached-3.1.3.tar.gz
$ cd php-memcached-3.1.3
