警告

本扩展模块是实验性的。该模块的行为，包括其函数的名称以及其它任何关于此模块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。我们提醒您在使用本扩展模块的同时自担风险。

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.

例子 1. ingres_connect() example
<?php $link = ingres_connect("mydb", "user", "pass") or die("Could not connect"); echo "Connected successfully"; ingres_close($link); ?>

例子 2. ingres_connect() example using default link
<?php ingres_connect("mydb", "user", "pass") or die("Could not connect"); echo "Connected successfully"; ingres_close(); ?>
