### How to install more PHP extensions
We provide two convenient scripts named `docker-php-ext-configure` and `docker-php-ext-install`, you can use them to easily install PHP extension.
We provide the helper scripts `docker-php-ext-configure`, `docker-php-ext-install`, and `docker-php-ext-enable` to more easily install PHP extensions.
#### PHP Core Extensions
For example, if you want to have a PHP-FPM image with `iconv`, `mcrypt` and `gd` extensions, you can inherit the base image that you like, and write your own `Dockerfile` like this:
```dockerfile
FROM php:5.6-fpm
# Install modules
FROM php:5-fpm
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libmcrypt-dev \
libpng12-dev \
&& docker-php-ext-install iconv mcrypt \
&& docker-php-ext-install -j$(nproc) iconv mcrypt \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install gd
CMD ["php-fpm"]
&& docker-php-ext-install -j$(nproc) gd
```
Remember, you must install dependencies for your extensions manually. If an extension needs custom `configure` arguments, you can use the `docker-php-ext-configure` script like this example.
### How to install PECL extensions
Some "extension" are in reality [PECL](https://pecl.php.net/) extension. To install a pecl extension you need to do this (for memcached) :
#### PECL extensions
Some extensions are not provided with the PHP source, but are instead available through [PECL](https://pecl.php.net/). To install a PECL extension, use `pecl install` to download and compile it, then use `docker-php-ext-enable` to enable it:
```dockerfile
FROM php:5.6-fpm
# Install pecl extension
RUN apt-get update && apt-get install -y libmemcached-dev && pecl install memcached
CMD ["php-fpm"]
FROM php:5-fpm
RUN apt-get update && apt-get install -y libmemcached-dev \
&& pecl install memcached \
&& docker-php-ext-enable memcached
```
#### Other extensions
Some extensions are not provided via either Core or PECL; these can be installed too, although the process is less automated:
```dockerfile
FROM php:5-apache
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o xcache.tar.gz \
&& mkdir -p xcache \
&& tar -xf xcache.tar.gz -C xcache --strip-components=1 \
&& rm xcache.tar.gz \
&& ( \
cd xcache \
&& phpize \
&& ./configure --enable-xcache \
&& make -j$(nproc) \
&& make install \
) \
&& rm -r xcache \
&& docker-php-ext-enable xcache
```
### Without a `Dockerfile`
