PHP 8.6 UPGRADE NOTES 1. Backward Incompatible Changes 2. New Features 3. Changes in SAPI modules 4. Deprecated Functionality 5. Changed Functions 6. New Functions 7. New Classes and Interfaces 8. Removed Extensions and SAPIs 9. Other Changes to Extensions 10. New Global Constants 11. Changes to INI File Handling 12. Windows Support 13. Other Changes 14. Performance Improvements ======================================== 1. Backward Incompatible Changes ======================================== - Phar: . Invalid values now throw in Phar::mungServer() instead of being silently ignored. ======================================== 2. New Features ======================================== - Core: . It is now possible to use reference assign on WeakMap without the key needing to be present beforehand. - Intl: . Added IntlNumberRangeFormatter class to format an interval of two numbers with a given skeleton, locale, IntlNumberRangeFormatter::COLLAPSE_AUTO, IntlNumberRangeFormatter::COLLAPSE_NONE, IntlNumberRangeFormatter::COLLAPSE_UNIT, IntlNumberRangeFormatter::COLLAPSE_ALL collapse and IntlNumberRangeFormatter::IDENTITY_FALLBACK_SINGLE_VALUE, IntlNumberRangeFormatter::IDENTITY_FALLBACK_APPROXIMATELY_OR_SINGLE_VALUE, IntlNumberRangeFormatter::IDENTITY_FALLBACK_APPROXIMATELY and IntlNumberRangeFormatter::IDENTITY_FALLBACK_RANGE identity fallbacks. It is supported from icu 63. - Streams: . Added stream socket context option so_reuseaddr that allows disabling address reuse (SO_REUSEADDR) and explicitly uses SO_EXCLUSIVEADDRUSE on Windows. ======================================== 3. Changes in SAPI modules ======================================== ======================================== 4. Deprecated Functionality ======================================== ======================================== 5. Changed Functions ======================================== - Phar: . Phar::mungServer() now supports reference values. - Zip: . ZipArchive::extractTo now raises a TypeError for the files argument if one or more of the entries is not a string. ======================================== 6. New Functions ======================================== ======================================== 7. New Classes and Interfaces ======================================== ======================================== 8. Removed Extensions and SAPIs ======================================== ======================================== 9. Other Changes to Extensions ======================================== - Hash: . The bundled version of xxHash was upgraded to 0.8.2. ======================================== 10. New Global Constants ======================================== ======================================== 11. Changes to INI File Handling ======================================== - Mysqli: . mysqli.default_port now checks the validity of the value which should be between 0 and 65535 included. - Opcache: . opcache.jit_debug accepts a new flag: ZEND_JIT_DEBUG_TRACE_EXIT_INFO_SRC. When used along with ZEND_JIT_DEBUG_TRACE_EXIT_INFO, the source of exit points is printed in exit info output, in debug builds. ======================================== 12. Windows Support ======================================== ======================================== 13. Other Changes ======================================== ======================================== 14. Performance Improvements ======================================== - Core: . `printf()` using only `%s` and `%d` will be compiled into the equivalent string interpolation, avoiding the overhead of a function call and repeatedly parsing the format string. . Arguments are now passed more efficiently to known constructors (e.g. when using new self()). - DOM: . Made splitText() faster and consume less memory. - JSON: . Improve performance of encoding arrays and objects. - Standard: . Improved performance of array_fill_keys(). . Improved performance of array_map() with multiple arrays passed. . Improved performance of array_unshift(). . Improved performance of array_walk(). . Improved performance of intval('+0b...', 2) and intval('0b...', 2). . Improved performance of str_split(). - Zip: . Avoid string copies in ZipArchive::addFromString().
