- session.bug_compat42
- session.bug_compat_warn
- y2k_compliance
- zend.ze1_compatibility_mode
- the following new php.ini directives were added:
- max_input_vars - specifies how many GET/POST/COOKIE input
variables may be accepted. The default value is 1000.
=============================
2. Reserved words and classes
=============================
- E_ALL now includes E_STRICT.
- The recommended production value for error_reporting changed to E_ALL &
~E_DEPRECATED & ~E_STRICT.
- Added new session support directives:
session.upload_progress.enabled
session.upload_progress.cleanup
session.upload_progress.prefix
session.upload_progress.name
session.upload_progress.freq
session.upload_progress.min_freq
- Added a zend.multibyte directive as a replacement of the PHP compile time
configuration option --enable-zend-multibyte. Now the Zend Engine always
contains code for multibyte support, which can be enabled or disabled at
runtime. Note: It doesn't make a lot of sense to enable this option if
ext/mbstring is not enabled, because most functionality is implemented by
mbstrings callbacks.
- Added zend.script_encoding. This value will be used unless a
"declare(encoding=...)" directive appears at the top of the script.
- Added enable_post_data_reading, which is enabled by default. When it's
disabled, the POST data is not read (or processed); the behavior is similar
to that of other request methods with body, like PUT. This allows reading
the raw POST data in multipart requests and reading/processing the POST data
in a stream fashion (through php://input) without having it copied in memory
multiple times.
- Added windows_show_crt_warning. This directive shows the CRT warnings when
enabled. These warnings were displayed by default until now. It is disabled
by default.
- Added cli.pager to set a pager for CLI interactive shell output.
- Added cli.prompt to configure the CLI interactive shell prompt.
- Added cli_server.color to enable the CLI web server to use ANSI color coding
in terminal outout.

================================
4. Changes to existing functions
================================
- array_combine now returns array() instead of FALSE when two empty arrays are
provided as parameters.
- Added an extra parameter to dns_get_record(), which allows requesting DNS
records by numeric type and makes the result include only the raw data of
the response.
- call_user_func_array no longer allows call-time pass by reference.
- htmlentities/htmlspecialchars are stricter in the code units they accept for
the asian encodings. For Big5-HKSCS, the octets 0x80 and 0xFF are rejected.
For GB2312/EUC-CN, the octets 0x8E, 0x8F, 0xA0 and 0xFF are rejected. For
SJIS, the octets 0x80, 0xA0, 0xFD, 0xFE and 0xFF are rejected, except maybe
after a valid starting byte. For EUC-JP, the octets 0xA0 and 0xFF are
rejected.
- htmlentities now emits an E_STRICT warning when used with asian characters,
- dns_get_record() has an extra parameter which allows requesting DNS records
by numeric type and makes the result include only the raw data of the
response.
- call_user_func_array() no longer allows call-time pass by reference.
- htmlentities() and htmlspecialchars() are stricter in the code units they
accept for the asian encodings. For Big5-HKSCS, the octets 0x80 and 0xFF are
rejected. For GB2312/EUC-CN, the octets 0x8E, 0x8F, 0xA0 and 0xFF are
rejected. For SJIS, the octets 0x80, 0xA0, 0xFD, 0xFE and 0xFF are rejected,
except maybe after a valid starting byte. For EUC-JP, the octets 0xA0 and
0xFF are rejected.
- htmlentities() now emits an E_STRICT warning when used with asian characters,
as in that case htmlentities has (and already had before this version) the
same functionality as htmlspecialchars.
- htmlentities no longer numerically encodes high characters for single-byte
- htmlentities() no longer numerically encodes high characters for single-byte
encodings (except when there's actually a corresponding named entity). This
behavior was not documented and was inconsistent with that for "UTF-8".
- html_entity_decode/htmlspecialchars_decode behave more consistently, now
decoding entities in malformed strings such as "&&amp;" or "&#&amp;".
- htmlentities/htmlspecialchars/html_entity_decode/htmlspecialchars_decode:
Added the flags ENT_HTML401, ENT_XML1, ENT_XHTML, and ENT_HTML5. The
behavior of these functions including, but not limited to, the characters
that are encoded and the entities that are decoded depend on the document
type that is specified by those flags.
- htmlentities/htmlspecialchars with !$double_encode do more strict checks on
the validity of the entities. Numerical entities are checked for a valid
range (0 to 0x10FFFF); if the flag ENT_DISALLOWED is given, the validity of
such numerical entity in the target document type is also checked. Named
entities are checked for necessary existence in the target document type
instead of only checking whether they were constituted by alphanumeric
characters.
- html_entity_decode() and htmlspecialchars_decode() behave more consistently,
now decoding entities in malformed strings such as "&&amp;" or "&#&amp;".
- htmlentities(), htmlspecialchars(), html_entity_decode(), and
htmlspecialchars_decode: Added the flags ENT_HTML401, ENT_XML1, ENT_XHTML,
and ENT_HTML5. The behavior of these functions including, but not limited to,
the characters that are encoded and the entities that are decoded depend on
the document type that is specified by those flags.
- htmlentities() and htmlspecialchars() with !$double_encode do more strict
checks on the validity of the entities. Numerical entities are checked for a
valid range (0 to 0x10FFFF); if the flag ENT_DISALLOWED is given, the
validity of such numerical entity in the target document type is also
checked. Named entities are checked for necessary existence in the target
document type instead of only checking whether they were constituted by
alphanumeric characters.
- The flag ENT_DISALLOWED was added. In addition to the behavior described in
the item before, it also makes htmlentities/htmlspecialchars substitute
characters that appear literally in the argument string and which are not
allowed in the target document type with U+FFFD (UTF-8) or &#xFFFD;.
the item before, it also makes htmlentities() and htmlspecialchars()
substitute characters that appear literally in the argument string and which
are not allowed in the target document type with U+FFFD (UTF-8) or &#xFFFD;.
- The flag ENT_SUBSTITUTE was added. This flag makes invalid multibyte
sequences be replaced by U+FFFD (UTF-8) or &#FFFD; by htmlspecialchars and
htmlentities. It is an alternative to the default behavior, which just
sequences be replaced by U+FFFD (UTF-8) or &#FFFD; by htmlspecialchars() and
htmlentities(). It is an alternative to the default behavior, which just
returns an empty string and to ENT_IGNORE, which is a security risk. The
behavior follows the recommendations of Unicode Technical Report #36.
- htmlspecialchars_decode/html_entity_decode now decode &apos; if the document
type is ENT_XML1, ENT_XHTML, or ENT_HTML5.
- htmlspecialchars_decode() and html_entity_decode() now decode &apos; if the
document type is ENT_XML1, ENT_XHTML, or ENT_HTML5.
- Charset detection with $charset == '' no longer turns to mbstring's
internal encoding defined through mb_internal_encoding(). Only the encoding
defined through the php.ini setting mbstring.internal_encoding is considered.
- number_format() no longer truncates multibyte decimal points and thousand
separators to the first byte.
- The third parameter ($matches) to preg_match_all() is now optional. If
omitted, the function will simply return the number of times the pattern was
matched in the subject and will have no other side effects.
- The second argument of scandir() now accepts SCANDIR_SORT_NONE (2) as a
possible value. This value results in scandir() performing no sorting: on
local filesystems, this allows files to be returned in native filesystem
order.
- stream_select() now preserves the keys of the passed array, be they numeric or
strings. This breaks code that iterated the resulting stream array using a
numeric index, but makes easier to identify which of the passed streams are
present in the result.
- stream_set_write_buffer() no longer disables the read buffer of a plain
stream when 0 is given as the second argument.
- stream_set_write_buffer() no longer changes the chunk size in socket streams.
- fclose() closes streams with resource refcount > 1; it doesn't merely
decrement the resource refcount.
- socket_set_options() and socket_get_options() now support multicast options.
- The raw data parameter in openssl_encrypt()/openssl_decrypt() is now an options
integer rather than a boolean. A value of true produces the same behaviour.
- The raw data parameter in openssl_encrypt() and openssl_decrypt() is now an
options integer rather than a boolean. A value of true produces the same
behavior.
- Write operations within XSLT (for example with the extension sax:output) are
disabled by default. You can define what is forbidden with the method
XsltProcess::setSecurityPrefs($options).
- Added AES support to OpenSSL.
- openssl_csr_new() expects the textual data to be in UTF-8.
- Added no padding option to openssl_encrypt()/openssl_decrypt().
- Added no-padding option to openssl_encrypt() and openssl_decrypt().
- Added a "no_ticket" SSL context option to disable the SessionTicket TLS
extension.
- Added new json_encode() options: JSON_PRETTY_PRINT, JSON_UNESCAPED_SLASHES,
JSON_NUMERIC_CHECK, JSON_BIGINT_AS_STRING, JSON_UNESCAPED_UNICODE.
- Added Tokyo Cabinet and Berkley DB 5 support to DBA extension.
- Added support for CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE
to cURL.
- Added optional argument to debug_backtrace() and debug_print_backtrace()
to limit the amount of stack frames returned.
- Fixed crypt_blowfish handling of 8-bit characters. crypt() in Blowfish mode
now supports hashes marked $2a$, $2x$, $2y$ and $2z$.
- mbstring now supports following encodings: Shift_JIS/UTF-8 Emoji,
JIS X0213:2004 (Shift_JIS-2004, EUC-JP-2004, ISO-2022-JP-2004),
MacJapanese (Shift_JIS), gb18030.
- Added encode/decode in hex format to mb_[en|de]code_numericentity().
- Added support for SORT_NATURAL and SORT_FLAG_CASE in array sort functions
(sort, rsort, ksort, krsort, asort, arsort and array_multisort).
- Added encode and decode in hex format to mb_encode_numericentity() and
mb_decode_numericentity().
- Added support for SORT_NATURAL and SORT_FLAG_CASE in array sort functions:
sort(), rsort(), ksort(), krsort(), asort(), arsort() and array_multisort().
- is_a() and is_subclass_of() now have third boolean parameter, which specifies
if the first argument can be a string class name. Default if false for is_a
and true for is_subclass_of() for BC reasons.
- ob_start() will now treat a chunk size of 1 as meaning 1 byte, rather than
the previous special case behaviour of treating it as 4096 bytes.
the previous special case behavior of treating it as 4096 bytes.
- idn_to_ascii() and idn_to_utf8() now take two extra parameters, one indicating
the variant (IDNA 2003 or UTS #46) and another, passed by reference, to return
details about the operation in case UTS #46 is chosen.
- gzencode() used with FORCE_DEFLATE now generates RFC1950 compliant data.
- ob_start() refuses to start multiple output buffers at once passed as
- ob_start() no longer starts multiple output buffers when passed
array("callback1", "callback2", "callback3", ...).

- DateTime::parseFromFormat() now has + modifier to allow trailing text in
the string to parse without throwing an error.

5. Changes to existing classes
==============================
- Classes that implement stream wrappers can define a method called
stream_truncate that will respond to truncation, e.g. through ftruncate.
Strictly speaking, this is an addition to the user-space stream wrapper
template, not a change to an actual class.
- Classes that implement stream wrappers can define a method called stream_metadata that
will be called on touch(), chmod(), chgrp(), chown().

- Added session.upload_progress.enabled, session.upload_progress.cleanup,
session.upload_progress.prefix, session.upload_progress.name,
session.upload_progress.freq, session.upload_progress.min_freq.
- Added zend.multibyte directive as a replacement of PHP compile time
configuration option --enable-zend-multibyte. Now ZE always contains code for
multibyte support, but may enable or disable it by zend.multibyte. It doesn't
make a lot of sense to enable this option without ext/mbstring, because the
most functionality is implemented by mbstrings callbacks.
- Added enable_post_data_reading, which is enabled by default. When it's
