### How to install more PHP extensions

We provide a convenient script named `docker-php-ext-install`, you can use it to
easily install PHP extension.

For example, if you want to have a PHP-FPM image with `gd` and `mcrypt`
extensions, you can inheriting the base image that you like, and write your own
Dockerfile like this:

Also, Dockerfile should be in backticks too. 👍


FROM php:5.5.19-fpm
# Install modules
RUN apt-get update && apt-get install -y \
apt-utils re2c \
zlib1g zlib1g-dbg zlib1g-dev zlibc \
libpng12-0 libpng12-dev libpng3 \
libjpeg9 libjpeg9-dbg libjpeg9-dev \
libmcrypt-dev libmcrypt4 mcrypt \
&& docker-php-ext-install gd mcrypt
CMD ["php-fpm"]

This will be inherited from the base image, won't it?

The following simple example works well for me (to get both gd and mcrypt):

FROM php:5.6-fpm
RUN apt-get update && apt-get install -y \
        libpng12-dev \
        libmcrypt-dev \
    && docker-php-ext-install gd mcrypt

The example is using php 5.5, which is probably more common than @tianon's example with 5.6 (since it is still quite new).

We should minimally change to php:5.5-fpm so that it does not have to be updated quite as often, rather than the 5.5.19-fpm which is already out of date.

Also, libjpeg9 (plus dev and dbg versions) does not exist in debian:jessie; it has been replaced by libjpeg62-turbo. Does it really need all those dependencies to build and later run? Can we simplify it like @tianon's example?

Updated.

I keep getting errors like 403 Forbidden [IP: 193.140.100.100 80], can't test it now.


Remember, you must install dependencies for your extensions manually.
