|
========================================
|
|
1. Backward Incompatible Changes
|
|
========================================
|
|
|
|
Core:
|
|
. The ext_skel utility has been completely redesigned with new options and
|
|
some old options removed. This is now written in PHP and has no external
|
|
dependencies.
|
|
. Support for BeOS has been dropped.
|
|
|
|
BCMath:
|
|
. All warnings thrown by BCMath functions are now using PHP's error handling.
|
|
Formerly some warnings have directly been written to stderr.
|
|
. bcmul() and bcpow() now return numbers with the requested scale. Formerly,
|
|
the returned numbers may have omitted trailing decimal zeroes.
|
|
|
|
SPL:
|
|
. If an SPL autoloader throws an exception, following autoloaders will not be
|
|
executed. Previously all autoloaders were executed and exceptions were
|
|
chained.
|
|
|
|
Standard:
|
|
. getimagesize() and related functions now report the mime type of BMP images
|
|
as image/bmp instead of image/x-ms-bmp, since the former has been registered
|
|
with the IANA (see RFC 7903).
|
|
|
|
========================================
|
|
2. New Features
|
|
========================================
|
|
|
|
Core:
|
|
. Array destructuring now supports reference assignments using the syntax
|
|
[&$a, [$b, &$c]] = $d. The same is also supported for list().
|
|
(RFC: https://wiki.php.net/rfc/list_reference_assignment)
|
|
|
|
BCMath:
|
|
. bcscale() can now also be used as getter to retrieve the current scale in use.
|
|
|
|
========================================
|
|
3. Changes in SAPI modules
|
|
========================================
|
|
|
|
========================================
|
|
4. Deprecated Functionality
|
|
========================================
|
|
|
|
========================================
|
|
5. Changed Functions
|
|
========================================
|
|
|
|
JSON:
|
|
. A new flag has been added, JSON_THROW_ON_ERROR, which can be used with
|
|
json_decode() or json_encode() and causes these functions to throw a
|
|
JsonException upon an error, instead of setting the global error state that
|
|
is retrieved with json_last_error(). JSON_PARTIAL_OUTPUT_ON_ERROR takes
|
|
precedence over JSON_THROW_ON_ERROR.
|
|
(RFC: https://wiki.php.net/rfc/json_throw_on_error)
|
|
|
|
Standard:
|
|
. debug_zval_dump() was changed to display recursive arrays and objects
|
|
in the same way as var_dump(). Now, it doesn't display them twice.
|
|
|
|
PCRE:
|
|
. preg_quote() now also escapes the '#' character.
|
|
|
|
========================================
|
|
6. New Functions
|
|
========================================
|
|
|
|
Date:
|
|
. Added the DateTime::createFromImmutable() method, which mirrors
|
|
DateTimeImmutable::createFromMutable().
|
|
|
|
GMP:
|
|
. Added gmp_binomial(n, k) for calculating binomial coefficients.
|
|
. Added gmp_lcm(a, b) for calculating the least common multiple.
|
|
. Added gmp_perfect_power(a) to check if number is a perfect power.
|
|
. Added gmp_kronecker(a, b) to compute the Kronecker symbol.
|
|
|
|
Intl:
|
|
. Added void Spoofchecker::setRestrictionLevel(int $level) method, available
|
|
when linked with ICU >= 58.1. Levels are represented as class constants
|
|
- Spoofchecker::ASCII
|
|
- Spoofchecker::HIGHLY_RESTRICTIVE
|
|
- Spoofchecker::MODERATELY_RESTRICTIVE
|
|
- Spoofchecker::MINIMALLY_RESTRICTIVE
|
|
- Spoofchecker::UNRESTRICTIVE
|
|
- Spoofchecker::SINGLE_SCRIPT_RESTRICTIVE
|
|
