Additional information, such as new release version, download, source file, additional information such as new releases, maintenance personnel information and change logs, etc., are here: http://pecl.php tutorial. net/package/memcached.

If libmemcached is installed in a non-standard path, use -- with-libmemcached-dir = dir to specify the path. dir is the prefix parameter for libmemcached installation. This path must contain the file include/libmemcached/memcached. h.

Zlib is required to support compression. For non-standard zlib libraries, use -- with-zlib-dir = dir to specify the zlib installation path. dir is the prefix parameter during zib installation.
