安装

安装此 PECL 扩展相关的信息可在手册中标题为 PECL 扩展的安装章节中找到。更多信息如新的发行版本、下载、源文件、维护人员信息及变更日志等，都在此处： » https://pecl.php.net/package/memcached.

如果libmemcached被安装在一个非标准路径，使用--with-libmemcached-dir=DIR 来指定路径，DIR就是libmemcached安装时的prefix参数。这个路径需要包含文件include/libmemcached/memcached.h。

如果要支持压缩就需要zlib。对于非标准安装的zlib库，使用--with-zlib-dir=DIR 来指定zlib安装路径，DIR就是zib安装时的prefix参数。

session处理器的支持默认是开启的。如果要关闭它，使用选项--disable-memcached-session。

For PHP 7 seems to work:



    $ sudo apt-get install memcached

    $ sudo apt-get install php-memcached

    $ sudo apachectl graceful



## php 7.2.19 / ubuntu 18.04.1



$mc = new Memcached();

$mc->addServer("localhost", 11211);

Do not lose your time to install it on Ubuntu just trying "sudo apt-get install php5-memcached". There is something you need to do that sure installing memcached. Anyway...





Step 1.


$ sudo apt-get install memcached


Step 2.


$ sudo apt-get install php5-memcached


Step 3.


$ sudo /etc/init.d/apache2 restart





Ready!





What about some test?





<?php


error_reporting(E_ALL & ~E_NOTICE);





$mc = new Memcached();


$mc->addServer("localhost", 11211);





$mc->set("foo", "Hello!");


$mc->set("bar", "Memcached...");





$arr = array(


    $mc->get("foo"),


    $mc->get("bar")


);


var_dump($arr);


?>





Hoping to help someone.

i'm planning on using membase for my website and i was really struggling to install the memcashed php client on ubuntu with pear, but actually there is an easier way:



$ sudo apt-get install php5-memcached



you dont even need to install the membase server first - this can be done afterwards. hope this helps someone!

At present memcached-1.0.0 does not compile with libmemcached-0.38. This is apparently due to libmemcached chaning the API.



For evidence, see this bug: http://pecl.php.net/bugs/bug.php?id=17070



Note: I am encountering the same 'memcached_st' has no member named 'hash' error on a Debian lenny amd_64 box.

If your server has --enable-json=shared as mine did, this extension requires you to have extension=json.so to load properly.
