Install PHP Memcache in docker php

install_memcache_docker.txt

PHP 5.6:
RUN apt-get update \
  && apt-get install -y libmemcached11 libmemcachedutil2 build-essential libmemcached-dev libz-dev \
  && pecl install memcached \
  && echo extension=memcached.so >> /usr/local/etc/php/conf.d/memcached.ini \
  && apt-get remove -y build-essential libmemcached-dev libz-dev \
  && apt-get autoremove -y \
  && apt-get clean \
  && rm -rf /tmp/pear

PHP 7:
git clone https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
  && cd /usr/src/php/ext/memcached && git checkout -b php7 origin/php7 \
  && docker-php-ext-configure memcached \
  && docker-php-ext-install memcached 

On PHP 7, you should then install ZLIB first before installing MEMCACHED

RUN apt-get update && apt-get install --no-install-recommends -y
libzip-dev
zlibc
zlib1g
&& docker-php-ext-configure zip --with-libzip
&& docker-php-ext-install zip

retry installing memcached

Simplified way

RUN apt-get update && apt-get install --no-install-recommends -y memcached libmemcached-tools libzip-dev zlibc zlib1g \
  && docker-php-ext-configure zip --with-libzip \
  && docker-php-ext-install zip \
  && git clone https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
  && cd /usr/src/php/ext/memcached && git checkout -b php7 origin/php7 \
  && docker-php-ext-configure memcached \
  && docker-php-ext-install memcached

Thank you vinnyfs89 this worked for me after adding libmemcached-dev and git in debian 9 docker image

apt-get update \
&& apt-get install --no-install-recommends -y memcached libmemcached-tools libzip-dev zlibc zlib1g  git  libmemcached-dev \
&& docker-php-ext-configure zip --with-libzip \
&& docker-php-ext-install zip \
&& git clone https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached && cd /usr/src/php/ext/memcached \
&& git checkout -b php7 origin/php7 \
&& docker-php-ext-configure memcached   && docker-php-ext-install memcached 

Simplified way

RUN apt-get update && apt-get install --no-install-recommends -y memcached libmemcached-tools libzip-dev zlibc zlib1g \
  && docker-php-ext-configure zip --with-libzip \
  && docker-php-ext-install zip \
  && git clone https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
  && cd /usr/src/php/ext/memcached && git checkout -b php7 origin/php7 \
  && docker-php-ext-configure memcached \
  && docker-php-ext-install memcached

I m getting the following error while using the same commands:
checking for libmemcached location... configure: error: memcached support requires libmemcached. Use --with-libmemcached-dir=<DIR> to specify the prefix where libmemcached headers and library are located

EDIT:
I managed to resolve the issue by the solution given on:
php-memcached-dev/php-memcached#408

you don't need to switch the branch to php7 now, for the master branch has supported it. Or you can just download the latest release, unzip and install as the same.

I got the same error as @StEvUgnIn . Tried a view variations of the compression libraries but still no success...

I don't remember what we did with my colleague, but I would suggest to look into the configuration of your httpd server.
