sapi_cli_server_send_headers() sent the header buffer through php_cli_server_client_send_through() but dropped the return value, so it always reported SAPI_HEADER_SENT_SUCCESSFULLY, even when the send failed and php_handle_aborted_connection() did not bail out (ignore_user_abort=1). It now compares the send result against the buffer length and returns SAPI_HEADER_SEND_FAILED when it comes up short. php_cli_server_client_send_through() itself returned the number of bytes left on failure, which equals str_len when nothing was sent: the same value it returns on success. It now returns the number of bytes actually sent on both paths. Since sapi_send_headers() resets headers_sent on SAPI_HEADER_SEND_FAILED, a headers_written flag on the client guards against rebuilding and resending the whole header block on every subsequent output write.

…ams (php#23282) Keep the native archive state alive independently of the ZipArchive object, allowing streams to remain valid without retaining the object itself.
uloc_getKeywordValue failure destroyed the result array and returned without uenum_close(). Close the enumeration on that path. The success path already closes it. Audited the other uenum_close site in this file (acceptLanguage). Closes phpGH-23351
stream_bucket_prepend()/append() assumed a successful zend_read_property() of StreamBucket::$data always yields a string, but for an unset typed property it throws while returning &EG(uninitialized_zval), so Z_STRLEN_P() dereferenced a NULL string pointer and crashed when the brigade was consumed. Reject non-string reads up front (rethrowing any pending exception) so the bucket is never re-attached with undefined data; the sibling $bucket property path is already safe because zend_fetch_resource_ex() rejects non-resources.

stream_bucket_prepend() and stream_bucket_append() assumed that a successful zend_read_property() of the typed StreamBucket::$data property always yields a string, but when the property has been unset in the filter callback the read throws while returning &EG(uninitialized_zval), so Z_STRLEN_P() dereferenced a NULL string pointer and crashed once the brigade was consumed. The fix rejects non-string reads up front, rethrowing any pending exception, so a bucket is never re-attached with undefined data. The sibling $bucket property path is already safe because zend_fetch_resource_ex() rejects non-resources. A regression test is included.
