# This list comes mainly from:
# - https://www.php.net/manual/en/ini.core.php
# - https://www.php.net/manual/en/ini.list.php
#
# There are additional directives defined in some of the modules, that can be parsed from each modules's configuration page:
# - https://www.php.net/manual/en/$book.configuration.php (book comes from funcref.php)
#
# As the source code is in docbook format with many dependencies, the easiest
# way to get it is using an xpath parser on the ini list and getting all
# using '//table/tbody/tr/td[1]'. A simple helper tool you can use is https://www.videlibri.de/xidel.html
#
# Small post-processing is needed to remove numbers coming from a column,
# and `*` chars (e.g. `pdo.dsn.*`).
# Also removed single words like `from` to prevent FP.
#
# Example usage:
# `xidel https://www.php.net/manual/en/ini.core.php https://www.php.net/manual/en/ini.list.php --xpath '//table/tbody/tr/td[1]' | sort | uniq`
#
# And for configuration in submodules:
#
# for book in $(xidel  https://www.php.net/manual/en/funcref.php -e '//a/extract(@href, "book\.(.+)\.php", 1)[. != ""]')                                                                                                 ─╯
# do
#   xidel https://www.php.net/manual/en/$book.configuration.php --xpath '//table/tbody/tr/td[1]' >> php-config-directives.txt
# done
#
# ** Remember to always `sort` the output so its easy to spot the changes, and remove duplicates if any.
