Prevent bit shift count wrapping quirkiness on some CPUs for left shift
Cast NaN and Infinity to zero
Updated >> 64-bit tests
...
So we can use it there as well...
For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just move that one struct into
zend_types.h.
* Removed ini options, safe_mode*
* Removed --enable-safe-mode --with-exec-dir configure options on Unix
* Updated extensions, SAPI's and core
* php_get_current_user() is now declared in main.c, thrus no need to include safe_mode.h anymore
[DOC] proto void header_remove([string header_name])
Removes an HTTP header previously set using header()
The header_name parameter is optionnal, all headers are
removed if it is not set
[SAPIs] The header_handler callback in sapi_module_struct has
been changed, it now take a new argument.
When it is set to SAPI_HEADER_DELETE, sapi_header->header is
the name of an header, header_handler has to delete it.
When it is set to SAPI_HEADER_DELETE_ALL, header_handler has
to delete all headers.
When sapi_header_op_enum is SAPI_HEADER_ADD or _REPLACE,
sapi_header->header is in the form "Name: value", header_handler
has to add or replace the given header.
In all cases, header_handler must not free sapi_header or
sapi_header->header. SAPI_HEADER_ADD must be returned if the
header has been added or replaced, or 0 in other cases.
