+
+# Create a dedicated PHP-FPM config
+#
+# usage: ynh_config_add_phpfpm
+#
+# This will automatically generate an appropriate PHP-FPM configuration for this app.
+#
+# The resulting configuration will be deployed to the appropriate place:
+# `/etc/php/$php_version/fpm/pool.d/$app.conf`
+#
+# If the app provides a `conf/extra_php-fpm.conf` template, it will be appended
+# to the generated configuration. (In the vast majority of cases, this shouldnt
+# be necessary)
+#
+# $php_version should be defined prior to calling this helper, but there should
+# be no reason to manually set it, as it is automatically set by the apt
+# helpers/resources when installing phpX.Y dependencies (PHP apps should at
+# least install phpX.Y-fpm using the `apt` helper/resource)
+#
+# `$php_group` can be defined as a global (from `_common.sh`) if the worker
+# processes should run with a different group than `$app`
+#
+# Additional "pm" and "php_admin_value" settings which are meant to be possibly
+# configurable by admins from a future standard config panel at some point,
+# related to performance and availability of the app, for which tweaking may be
+# required if the app is used by "plenty" of users and other memory/CPU load
+# considerations....
+#
+# If you have good reasons to be willing to use different
+# defaults than the one set by this helper (while still allowing admin to
+# override it) you should use `ynh_app_setting_set_default`
+#
+# - `$php_upload_max_filezise`: corresponds upload_max_filesize and post_max_size. Defaults to 50M
+# - `$php_process_management`: corresponds to "pm" (ondemand, dynamic, static). Defaults to ondemand
+# - `$php_max_children`: by default, computed from "total RAM" divided by 40, cf `_default_php_max_children`
+# - `$php_memory_limit`: by default, 128M (from global php.ini)
+#
+# Note that if $php_process_management is set to "dynamic", then these
+# variables MUST be defined prior to calling the helper (no default value) ...
+# Check PHP-FPM's manual for more info on what these are (: ...
+#
+# - `$php_start_servers`
+# - `$php_min_spare_servers`
