========================================
|
|
1. Backward Incompatible Changes
|
|
========================================
|
|
|
|
- Core
|
|
. Added null coalesce operator (??).
|
|
(RFC: https://wiki.php.net/rfc/isset_ternary)
|
|
. list() now always supports ArrayAccess and never supports strings.
|
|
Previously both were accepted in some situations and not in others.
|
|
(RFC: https://wiki.php.net/rfc/fix_list_behavior_inconsistency)
|
|
. Bitwise shifts by negative numbers of bits are disallowed (throws E_WARNING
|
|
and gives FALSE, like a division by zero).
|
|
. Left bitwise shifts by a number of bits beyond the bit width of an integer
|
|
will always result in 0, even on CPUs which wrap around.
|
|
. Right bitwise shifts by a number of bits beyond the bit width of an integer
|
|
will always result in 0 or -1 (depending on sign), even on CPUs which wrap
|
|
around.
|
|
. Removed ASP (<%) and script (<script language=php>) tags.
|
|
(RFC: https://wiki.php.net/rfc/remove_alternative_php_tags)
|
|
|
|
- DBA
|
|
. dba_delete() now returns false if the key was not found for the inifile
|
|
handler, too.
|
|
|
|
- GMP
|
|
. Requires libgmp version 4.2 or newer now.
|
|
. gmp_setbit() and gmp_clrbit() now return FALSE for negative indices, making
|
|
them consistent with other GMP functions.
|
|
|
|
========================================
|
|
2. New Features
|
|
========================================
|
|
|
|
- Core
|
|
. Support for strings with length >= 2^31 bytes in 64 bit builds
|
|
. Closure::call() method added
|
|
|
|
- Standard
|
|
. intdiv() function for integer division added.
|
|
|
|
========================================
|
|
3. Changes in SAPI modules
|
|
========================================
|
|
|
|
- FPM
|
|
. Fixed bug #65933 (Cannot specify config lines longer than 1024 bytes).
