# maxdb_connect

(PECL)

maxdb_connect

(no version information, might be only in CVS)

maxdb() -- 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]]]]]] )

Object oriented style (constructor):

class maxdb {
__construct ( [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

Exemplo 1. Object oriented style
`<?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } printf("Host information: %s\n", $maxdb->host_info); /* close connection */ $maxdb->close(); ?>`

Exemplo 2. Procedural style
`<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$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
