We recommend that you add a custom `php.ini` configuration. `COPY` it into `/usr/local/etc/php` by adding one more line to the Dockerfile above and running the same commands to build and run:
```dockerfile
FROM %%IMAGE%%:7.2-apache
COPY config/php.ini /usr/local/etc/php/
COPY src/ /var/www/html/
```
Where `src/` is the directory containing all your PHP code and `config/` contains your `php.ini` file.
We recommend that you add a `php.ini` configuration file, see the "Configuration" section for details.
### Without a `Dockerfile`

The *proper* solution to this error is to either use `FROM debian:XXX` and install Debian's PHP packages directly, or to use `docker-php-ext-install`, `pecl`, and/or `phpize` to install the necessary additional extensions and utilities.
## Configuration
This image ships with the default [`php.ini-development`](https://github.com/php/php-src/blob/master/php.ini-development) and [`php.ini-production`](https://github.com/php/php-src/blob/master/php.ini-production) configuration files.
It is *strongly* recommended to use the production config for images used in production environments!
The default config can be customized by copying configuration files into the `$PHP_INI_DIR/conf.d/` directory.
### Example
```dockerfile
FROM %%IMAGE%%:7.2-fpm-alpine
# Use the default production configuration
RUN mv $PHP_INI_DIR/php.ini-production $PHP_INI_DIR/php.ini
# Override with custom opcache settings
COPY config/opcache.ini $PHP_INI_DIR/conf.d/
```
Where `config/` contains your custom configuration files.
