PHP 8.6 INTERNALS UPGRADE NOTES
1. Internal API changes
2. Build system changes
3. Module changes
4. OpCode changes
5. SAPI changes
========================
1. Internal API changes
========================
. ZSTR_INIT_LITERAL(), zend_string_starts_with_literal(), and
zend_string_starts_with_literal_ci() now support strings containing NUL
bytes. Passing non-literal char* is no longer supported.
. The misnamed ZVAL_IS_NULL() has been removed. Use Z_ISNULL() instead.
. New zend_class_entry.ce_flags2 and zend_function.fn_flags2 fields were
added, given the primary flags were running out of bits.
. The zval_is_true() alias of zend_is_true() has been removed. Call
zend_is_true() directly instead.
. The _zval_get_*() compatibility macros for PHP 7.2 have been removed
call the variant without the leading underscore instead.
Affected: _zval_get_long, _zval_get_double, _zval_get_string,
_zval_get_long_func, _zval_get_double_func, _zval_get_string_func
. CHECK_ZVAL_NULL_PATH() and CHECK_NULL_PATH() have been removed, use
zend_str_has_nul_byte(Z_STR_P(...)) and zend_char_has_nul_byte()
respectively.
. ZEND_LTOA() (and ZEND_LTOA_BUF_LEN) has been removed, as it was
unsafe. Directly use ZEND_LONG_FMT with a function from the
printf family.
. The zval_dtor() alias of zval_ptr_dtor_nogc() has been removed.
Call zval_ptr_dtor_nogc() directly instead.
. The internal zend_copy_parameters_array() function is no longer exposed.
. The zend_make_callable() function has been removed, if a callable zval
needs to be obtained use the zend_get_callable_zval_from_fcc() function
instead. If this was used to store a callable, then an FCC should be
stored instead.
. The zend_active_function{_ex}() functions now return a const zend_function
pointer.
. The zend_get_call_trampoline_func() API now takes the __call or
__callStatic zend_function* instead of a CE and a boolean argument.
. The zend_set_hash_symbol() API has been removed.
. Added zend_hash_str_lookup().
. The WRONG_PARAM_COUNT and ZEND_WRONG_PARAM_COUNT() macros have been
removed. Call zend_wrong_param_count(); followed by RETURN_THROWS();
instead.
. PHP_HAVE_STREAMS macro removed from <php.h>.
========================
2. Build system changes
========================
========================
3. Module changes
========================
- ext/xml:
. Removed the XML_ExpatVersion() libxml compatibility wrapper,
as it was unused.
. Removed the XML_GetCurrentByteCount() libxml compatibility wrapper,
as it was unused and could return the wrong result.
========================
4. OpCode changes
========================
========================
5. SAPI changes
