## #23008 — Michael Wallner — 2006-04-28T14:19:13+00:00

Hi,

I wonder if the few places where entries are added and the terminating null
of the array key is not honored are intentional or by mistake?

AFAICS at least these places are affected:
	- Registered PHP Streams
	- Registered Stream Socket Transports
	- Registered Stream Filters
	- URL-Rewriter vars
	- PDO drivers
	- GIF logo UIDs
	- LD_LIBRARY_PATH (dunno where this comes from)

JFYI, I stumbled accross these while placing a debug output in zend_hash_update(),
because I faced some weird behaviour when `print_r()` showed array entries
not accessible by array key (caused by my own mistakes).

Thanks,

These are all intentional; there is no need to store nor compare
against that NUL byte.
