Pantheon php.ini settings differences

These may change of course, but here are the current differences I see in my local Homebrew php.ini file versus what Pantheon uses:

allow_call_time_pass_reference = Off
realpath_cache_size = "800k"
register_long_arrays = Off
realpath_cache_ttl = "86400"
include_path = ".:/usr/share/pear:/usr/share/php"
expose_php = Off
max_execution_time = 120
max_input_time = 900
max_input_vars = 10000
post_max_size = 100M
error_reporting = E_ALL & ~E_DEPRECATED & ~E_NOTICE
ignore_repeated_errors = on
html_errors = off
session.cache_expire = 200000
session.cookie_lifetime = 2000000
session.gc_maxlifetime = 200000
session.save_handler = user
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.fast_shutdown=1

They also use APCu and NewRelic.
