ingres_connect --  Open a connection to an Ingres II database

Description

resource ingres_connect ( [string database [, string username [, string password]]] )

Warning

This function is EXPERIMENTAL . The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

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.

Example 1. ingres_connect() example

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

Example 2. ingres_connect() example using default link

<?php
    ingres_connect("mydb", "user", "pass")
        or die("Could not connect");
    echo "Connected successfully";
    ingres_close();
?>
