# maxdb_connect

(no version information, might be only in CVS)

maxdb_connect -- Open a new connection to the MaxDB server

## Description

Procedural style

resource maxdb_connect ( [string host [, string username [, string passwd [, string dbname [, int port [, string socket]]]]]] )

The maxdb_connect() function attempts to open a connection to the MaxDB Server running on host which can be either a host name or an IP address. Passing the string "localhost" to this parameter, the local host is assumed. If successful, the maxdb_connect() will return an resource representing the connection to the database, or `FALSE` on failure.

The username and password parameters specify the username and password under which to connect to the MaxDB server. If the password is not provided (the `NULL` value is passed), the MaxDB server will attempt to authenticate the user against the maxdb.default_pw in `php.ini`.

The dbname parameter if provided will specify the default database to be used when performing queries. If not provied, the entry maxdb.default_db in `php.ini` is used.

The port and socket parameters are ignored for the MaxDB server.

## Return values

Returns a resource which represents the connection to a MaxDB Server or `FALSE` if the connection failed.

## Example

範例 1. Procedural style

`<?php $link = maxdb_connect("localhost", "MONA", "RED"); /* check connection */ if (!$link) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } printf("Host information: %s\n", maxdb_get_host_info($link)); /* close connection */ maxdb_close($link); ?>`

The above examples would produce the following output:

    Host information: localhost
