(PECL maxdb:7.5.00.24-7.6.00.38)

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):

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.

### Examples

Example#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();
?>`

Example#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
