From: walter at wjd dot nu Operating system: linux/debian, linux/ubuntu PHP version: 4.4.7 PHP Bug Type: Sybase-ct (ctlib) related Bug description: mssql_select_db changes all open connections OR new_link boolean doesn't work
Description: ------------ The new_link boolean in mssql_connect does not do what its supposed to do for me. When select_db'ing the second open link, the first link gets affected. var_dump tells me that both connections are the same. When I'm using mssql_pconnect instead of connect, I do get another resource number for the second connection, but the bug that selects the wrong database, still remains. Is this a wrong version thing? Does mssql_select_db/mssql_query use the wrong database handle? Does the new_link boolean not work as it should? I'm lying about the PHP version in the select box; I don't have that exact version lying around. But I've seen that this bug was dismissed in March 2006 (http://bugs.php.net/bug.php?id=36639) when there was no 4.4.7.
