The <span class="function"><strong>maxdb_connect()</strong></span> function attempts to open a connection to the MaxDB Server
running on <em><code class="parameter">host</code></em> 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 <span class="function"><strong>maxdb_connect()</strong></span>
will return an resource representing the connection to the database or <strong><code>FALSE</code></strong> on failure.

<p class="para">
The <em><code class="parameter">username</code></em> and <em><code class="parameter">password</code></em> parameters specify the
username and password under which to connect to the MaxDB server. If the password is not provided
(the <strong><code>NULL</code></strong> value is passed), the MaxDB server will attempt to authenticate the user against
the <em><code class="parameter">maxdb.default_pw</code></em> in <var class="filename">php.ini</var>.
</p>
<p class="para">
The <em><code class="parameter">dbname</code></em> parameter if provided will specify the default database to be
used when performing queries. If not provied, the entry <em><code class="parameter">maxdb.default_db</code></em>
in <var class="filename">php.ini</var> is used.

The <em><code class="parameter">port</code></em> and <em><code class="parameter">socket</code></em> parameters are
