========================================
1. Backward Incompatible Changes
========================================
- Core:
. Methods with the same name as the class are no longer interpreted as
constructors. The __construct() method should be used instead.
. Removed ability to call non-static methods statically.
. Removed (unset) cast.
. Removed track_errors ini directive. This means that $php_errormsg is no
longer available. The error_get_last() function may be used instead.
. Removed the ability to define case-insensitive constants. The third
argument to define() may no longer be true.
. Access to undefined constants now always results in an Error exception.
Previously, unqualified constant accesses resulted in a warning and were
interpreted as strings.
. Removed ability to specify an autoloader using an __autoload() function.
spl_autoload_register() should be used instead.
. Removed the $errcontext argument for custom error handlers.
. Removed create_function(). Anonymous functions may be used instead.
. Removed each(). foreach or ArrayIterator should be used instead.
. Removed ability to unbind $this from closures that were created from a
method, using Closure::fromCallable() or ReflectionMethod::getClosure().
. Any array that has a number n as its first numeric key will use n+1 for
its next implicit key. Even if n is negative.
RFC: https://wiki.php.net/rfc/negative_array_index
- Date:
. mktime() and gmmktime() now require at least one argument. time() can be
used to get the current timestamp.
- Exif:
. Removed read_exif_data(). exif_read_data() should be used instead.
- Filter:
. The FILTER_FLAG_SCHEME_REQUIRED and FILTER_FLAG_HOST_REQUIRED flags for the
FILTER_VALIDATE_URL filter have been removed. The scheme and host are (and
have been) always required.
- GD:
. The deprecated function image2wbmp() has been removed.
RFC: https://wiki.php.net/rfc/image2wbmp
. The deprecated functions png2wbmp() and jpeg2wbmp() have been removed.
RFC: https://wiki.php.net/rfc/deprecate-png-jpeg-2wbmp
. The default $mode parameter of imagecropauto() no longer accepts -1.
IMG_CROP_DEFAULT should be used instead.
- GMP:
. gmp_random() has been removed. One of gmp_random_range() or
gmp_random_bits() should be used instead.
- Intl:
. The deprecated constant INTL_IDNA_VARIANT_2003 has been removed.
RFC: https://wiki.php.net/rfc/deprecate-and-remove-intl_idna_variant_2003
. The deprecated Normalizer::NONE constant has been removed.
- LDAP:
. The deprecated function ldap_sort has been removed.
- Mbstring:
. The mbstring.func_overload directive has been removed. The related
MB_OVERLOAD_MAIL, MB_OVERLOAD_STRING, and MB_OVERLOAD_REGEX constants have
also been removed. Finally, the "func_overload" and "func_overload_list"
entries in mb_get_info() have been removed.
. mb_parse_str() can no longer be used without specifying a result array.
. A number of deprecated mbregex aliases have been removed. See the following
list for which functions should be used instead:
* mbregex_encoding() -> mb_regex_encoding()
* mbereg() -> mb_ereg()
* mberegi() -> mb_eregi()
* mbereg_replace() -> mb_ereg_replace()
* mberegi_replace() -> mb_eregi_replace()
* mbsplit() -> mb_split()
* mbereg_match() -> mb_ereg_match()
* mbereg_search() -> mb_ereg_search()
* mbereg_search_pos() -> mb_ereg_search_pos()
* mbereg_search_regs() -> mb_ereg_search_regs()
* mbereg_search_init() -> mb_ereg_search_init()
* mbereg_search_getregs() -> mb_ereg_search_getregs()
* mbereg_search_getpos() -> mb_ereg_search_getpos()
* mbereg_search_setpos() -> mb_ereg_search_setpos()
. The 'e' modifier for mb_ereg_replace() has been removed.
mb_ereg_replace_callback() should be used instead.
. A non-string pattern argument to mb_ereg_replace() will now be interpreted
as a string instead of an ASCII codepoint. The previous behavior may be
restored with an explicit call to chr().
- Reflection:
. The following methods signatures have been changed:
* ReflectionClass::newInstance(mixed $args) -> ReflectionClass::newInstance([mixed ...$args])
* ReflectionFunction::invoke(mixed $args) -> ReflectionFunction::invoke(mixed ...$args)
* ReflectionMethod::invoke(object $object, mixed $args) -> ReflectionMethod::invoke(object $object [, mixed ...$args])
Inheriting classes implementing this method will now have to use
a compatible method signature.
- SPL:
. SplFileObject::fgetss() has been removed.
. SplHeap::compare($a, $b) now specifies a method signature. Inheriting
classes implementing this method will now have to use a compatible
method signature.
- Standard:
. assert() will no longer evaluate string arguments, instead they will be
treated like any other argument. assert($a == $b) should be used instead of
assert('$a == $b'). The assert.quiet_eval ini directive and
ASSERT_QUIET_EVAL constants have also been removed, as they would no longer
have any effect.
. parse_str() can no longer be used without specifying a result array.
. fgetss() has been removed.
. The string.strip_tags filter has been removed.
. The needle argument of strpos(), strrpos(), stripos(), strripos(), strstr(),
strchr(), strrchr(), and stristr() will now always be interpreted as a
string. Previously non-string needles were interpreted as an ASCII code
point. An explicit call to chr() can be used to restore the previous
behavior.
. The 'salt' option of password_hash() is no longer supported. If the 'salt'
option is used a warning is generated, the provided salt is ignored, and a
generated salt is used instead.
- Zlib:
. gzgetss() has been removed.
