[PHP-NOTES] note 130405 added to configuration.file

It is worth noting that  $PHP_INI_SCAN_DIR is **not** recursive, which offers flexibility in organizing configuration in base-environment fashion:

$ mkdir -p /tmp/php_conf/prod /tmp/php_conf/dev 
$ touch /tmp/php_conf/php.base.ini /tmp/php_conf/prod/php.ini /tmp/php_conf/dev/php.ini
$ export PHP_INI_SCAN_DIR="/tmp/php_conf:/tmp/php_conf/dev"
$ php --ini
//...
Scan for additional .ini files in: /tmp/php_conf:/tmp/php_conf/dev
Additional .ini files parsed:      /tmp/php_conf/php.base.ini,
/tmp/php_conf/dev/php.ini

Such behavior can be used with docker where whole a subtree of configs is mounted into a dev-container, with ability to control which set of files is loaded using an environment variable.
