Subject: have DB::isError return true if passed "null". Now you can more consistently
X-Git-Tag: php-4.0.5RC1~462
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b4378dcf80153d66caef456b451ebbf1fd82ee72;p=php

have DB::isError return true if passed "null". Now you can more consistently
use DB::isError(), since some of the db drivers return nulls from various
functions (like fetchRow()), and others don't... We should probably make all
of them just return errors. I did this for the mysql driver, as a start.
