Subject: [RFC] Removal of deprecated features
From: kalle@php.net (Kalle Sommer Nielsen)

Hey Everyone

I've put together a simple RFC[1] that lists features thats been
deprecated in 5.3, someone of them which I propose we remove in the
next version of PHP, depending on the version number. Most of the
features, which is listed below are taken from the old 6.0 NEWS[2]
file, and items from the old PHP6 TODO[3].

safe_mode/register_globals/register_long_arrays/magic_quotes_*/allow_call_time_pass_reference
 - Something we have long time been wanted to remove from PHP, I don't
see a big reason to keep those in the next version, even if its going
to be a 5.4, since we already removed things like
zend.ze1_compatibility_mode. See the magic quotes RFC[4].

define_syslog_variables and its associated function
 - Originally agreed to be removed in PHP6 during the 5.3 development,
if there is no objects then I will remove by the end of this weekend.

asp_tags
 - Proposed to be removed aswell, Tony had a patch for this[5].

sql_safe_mode
 - Theres currently an RFC in the works about this by Johannes[6].

session_register/session_is_registered/session_register
 - Only needed for register_globals, Hannes removed those in PHP6.

enable_dl
 - Is this really worth keeping, since dl() was disabled on almost all
SAPIs except for CLI/CGI/Embed?

Support for Freetype 1 and GD 1
 - Removed by Pierre in PHP6

Support for "continue" and "break" operators with non constant operands
 - Removed by Dmitry in PHP6.

Undocumented and incomplete support for strings in list() operator
 - Removed by Dmitry in PHP6 aswell.

detect_unicode/highlight_bg
 - Two ini values thats been marked as removed features from PHP6 in
the manual. Not sure about detect_unicode, but highlight_bg is pretty
pointless.

y2k_compliance
 - From the manual "Enforce year 2000 compliance (will cause problems
with non-compliant browsers)", we are in 2010, we should remove this
option and enable it by default and remove the checks. Perhaps Derick
got an insight here?

Class named constructors
 - A feature thats been marked in the manual as something that would
be removed in a future version of PHP6. It was not to be knowing ever
decided to be kept or not, but now with the recent removal of them in
namespaces then I don't see a big point in keeping them.


If there is anything I forgot then let me know and I will add it to
the RFC, else discussions away!
