Hi:

The enclosed patch makes the Sybase DBLib support compile against PHP 5
and ZE 2, fixes crashes in sybase_select_db() and sybase_affected_rows()
related to incorrect zval initialization, implements the missing
sybase_fetch_assoc(), removes a bunch of redundant calls to Z_STRLEN_PP()
in php_sybase_do_connect(), and checks the return value of malloc() in the one
place it's called. I've tested the modifications against a CVS snapshot of the
FreeTDS dblib.

If everything in the patch looks okay, could this be applied?

Thanks in advance,

Dave
