我有memcached安装了libmemcached.我也安装了igbinary.
这是我的PHP.ini：
; Directory in which the loadable extensions (modules) reside. ;extension_dir = "./" extension_dir = "/usr/local/lib/PHP/extensions/no-debug-non-zts-20060613/" extension=apc.so apc.enabled=1 apc.shm_size=128M extension=memcached.so session.save_handler=memcached session.save_path="127.0.0.1:11211" extension=igbinary.so session.serialize_handler=igbinary igbinary.compact_strings=On
.
当我运行PHPinfo()我看到igbinary被启用,但不是为memcached：
apc Serialization Support PHP,igbinary igbinary igbinary support enabled igbinary version 1.1.1 igbinary APC serializer ABI 0 Directive Local Value Master Value igbinary.compact_strings On On
关于memcached的PHPinfo()
memcached memcached support enabled Version 1.0.2 libmemcached version 0.51 Session support yes igbinary support no
最后一行：igbinary支持这个问题.奇怪的是,正如你可以看到,在apc的标题下有：序列化支持PHP,igbinary.
那么有人知道为什么我不能为memcached启用igbinary？
谢谢！
您可以检查Memcached :: HAVE_IGBINARY常量,以查看您的memcached扩展名是否使用–enable-memcached-igbinary进行编译.
