   ### <a id="engine-configurations"></a> HTTPD, Nginx, and PHP configuration
   
   The buildpack automatically configures HTTPD, Nginx, and PHP for your application.  This section explains how to modify the configuration.
   
  -The `.bp-config` directory in your application can contain configuration overrides for these components. Name the directories `httpd`, `nginx`, and `php`. We recommend that you use [php.ini.d](#php_ini_d) or [fpm.d](#fpm_d)).

  -<p class='note'><strong>NOTE</strong>: If you override the php.ini or php-fpm.ini files many other forms of configuration will not work.</p>
  +<p class='note'><strong>NOTE</strong>: If you override the <code>php.ini</code> or <code>php-fpm.ini</code> files, many other forms of configuration will not work.</p>
   
   For example:
   ```
  
positive.code: 
  In this example, the `httpd-logging.conf` file overrides the one provided by the buildpack. We recommend that you copy the default from the buildpack and modify it.
  
  The default configuration files are found in the [PHP Buildpack `/defaults/config` directory](https://github.com/cloudfoundry/php-buildpack/tree/master/defaults/config)
  
  Take care when modifying configurations, as it might cause your application to fail, or cause Cloud Foundry to fail to stage your application.
  
  You can add your own configuration files. The components will not know about these, so you must ensure that they are included. For example, you can add an include directive to the [httpd configuration](https://github.com/cloudfoundry/php-buildpack/blob/master/defaults/config/httpd/2.4.x/httpd.conf) to include your file:
  
  
negative.code: 
  #### <a id="php_ini_d"></a> .bp-config/php/php.ini.d/
  
  The buildpack adds any `.bp-config/php/php.ini.d/FILE-NAME.ini` files it finds in the application to the PHP configuration. You can use this to change any value acceptable to `php.ini`. See [http://php.net/manual/en/ini.list.php](http://php.net/manual/en/ini.list.php) for a list of directives.
  
  For example, adding a file `.bp-config/php/php.ini.d/something.ini` to your app, with the following contents, overrides both the default charset and mimetype.
  
  ```
  default_charset="UTF-8"
  default_mimetype="text/xhtml"
  ```
  
  ##### Precedence
  
  In order of highest precedence, php configuration values come from the following sources:
  
  * php scripts using `ini_set()` to manually override config files
  * user.ini files for local values
  * .bp-config/php/php.ini.d to override master value, but not local values from user.ini files
  
  #### <a id="fpm_d"></a> .bp-config/php/fpm.d/
  
  The buildpack adds any `.bp-config/php/fpm.d` files it finds in the application to the PHP-FPM configuration. You can use this to change any value acceptable to `php-fpm.ini`. See [http://php.net/manual/en/install.fpm.configuration.php](http://php.net/manual/en/install.fpm.configuration.php) for a list of directives.
  
  ### <a id="php-extensions"></a> PHP Extensions
  
  The buildpack adds any `.bp-config/php/php.ini.d/FILE-NAME.ini` files it finds in the application to the PHP configuration. You can use this to enable PHP or ZEND extensions. For example:
  
  
  ```
