[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.
- Added ZEND_FETCH_RESOURCE2_NO_RETURN() (a version of ZEND_FETCH_RESOURCE2 but without the ZEND_VERIFY_RESOURCE() which contains RETURN_FALSE)
- Fixed bug #46543 (ibase_trans() memory leaks when using wrong parameters)
to find out if the return_value had the correct number of elements was
definitely needed. Simply added a difference to both dbh and stmt to
make sure that the error info always has 3 elements.
- Bug #44154 (pdo->errorInfo doesn't always return three elements)
- Now pdo->errorInfo() AND stmt->errorInfo() return three elements.
- [DOC] Make sure that not only the pdo->errorInfo() is returning 3 elms, but
also the PDOStatement object
# [DOC] If a second call is made to sybase_connect() with the same arguments
# no new link will be established, but instead, the link identifier of the
# already opened link will be returned. The new parameter modifies this
# behavior and makes sybase_connect() always open a new link, even if
# sybase_connect() was called before with the same parameters.
