    Installation

    Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » https://pecl.php.net/package/memcached.

    If libmemcached is installed in a non-standard location, use --with-libmemcached-dir=DIR switch, where DIR is the libmemcached install prefix. This directory has to contain the include/libmemcached/memcached.h file.

    Zlib is required for compression support. To specify non-standard installation of Zlib, use --with-zlib-dir=DIR switch, where DIR is the Zlib install prefix.

    Session handler support is enabled by default. To disable it, use --disable-memcached-session switch.

    SASL authentication support is disabled by default. To enable it, use --enable-memcached-sasl switch. This requires that libsasl2 has been installed and that libmemcached has been built with SASL support enabled.

    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.

    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);
    ...

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

    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.
