ingres_connect ( [string database [, string username [, string password]]] )
| 警告 |
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随
PHP 以后的发布而改变。使用本函数风险自担。 |
Returns a Ingres II link resource on success, or FALSE on
failure.
ingres_connect() opens a connection with the
Ingres database designated by database,
which follows the syntax
[node_id::]dbname[/svr_class].
If some parameters are missing, ingres_connect()
uses the values in php.ini for
ingres.default_database,
ingres.default_user, and
ingres.default_password.
The connection is closed when the script ends or when
ingres_close() is called on this link.
All the other ingres functions use the last opened link as a
default, so you need to store the returned value only if you use
more than one link at a time.
