#
# Description
#   Updates each user's 'php.ini' file so it's compatible with EA4.
#
# Conditions (ALL must be met for this script to run)
#   1. This is being run by the migrate_ea3_to_ea4 script.
#   2. The system default PHP version is assigned to the mod_suphp
#      Apache handler.
#   3. User is assigned to the system default PHP version.
#   4. The user has defined the 'suPHP_ConfigPath' setting within
#      an .htaccess file in the docroot of a vhost.
#
# Design
#   You'll notice 4 packages in this script.  These are separate
#   because:
#    1. It's overkill right now to create a whole new RPM package
#       which would contain the code we need to correctly parse
#       PHP ini files, get it into cpanel & whm, etc.
#    2. This used to be broken up into 2 scripts and designed to
#       allow future cmd-line execution.  However, it was too slow.
#       In an effort to speed it up (1.5 hrs to 5 mins against
#       10k accounts), the files were merged (/bin/cat a b > c) and
#       it was easier to combine the files and keep the packages
#       intact.
#
#   The 4 packages in here are as follows:
#    - Parse::PHP::Ini -- logic to parse/merge/render PHP ini files
#    - ea_convert_php_ini_file -- logic to convert a single php ini file
#    - ea_convert_php_ini_system -- logic to convert an entire
#        cpanel system
#    - main -- main script interface
#
# TODO:
#   1. Allow user to manually run this script to convert the system at-will.
#   2. Allow script to convert a vhost's ini files assigned to a php version
#      other than the system default.
#   3. Allow script to run if the php version is assigned to a non-suphp handler.
#   4. Allow user to convert an individual ini file.
#
# !!! This should only be run during migration !!!
