Subject: Fix scheme_getall() function so that data returned by user is always
X-Git-Tag: php-4.3.0RC1~359
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d2275d91950531560cdb8925317293e2e7a46385;p=php

Fix scheme_getall() function so that data returned by user is always
converted to string except when script returns FALSE or NULL. In this case
signal sablotron that we are not able to handle requested scheme.
