This method is not meant to be called directly. The preferred way to create
an instance of MongoDB is through <span class="function"><a href="mongoclient.get.html" class="function">MongoClient::__get()</a></span> or
<span class="function"><a href="mongoclient.selectdb.html" class="function">MongoClient::selectDB()</a></span>.
</p>
<p class="para">
If you're ignoring the previous paragraph and want to call it directly you
can do so:
</p>
<div class="example-contents">
<div class="phpcode"><code><span style="color: #000000">
<span style="color: #0000BB"><?php<br /><br />$m </span><span style="color: #007700">= new </span><span style="color: #0000BB">MongoClient</span><span style="color: #007700">();<br /></span><span style="color: #0000BB">$db </span><span style="color: #007700">= new </span><span style="color: #0000BB">MongoDB</span><span style="color: #007700">(</span><span style="color: #0000BB">$m</span><span style="color: #007700">, </span><span style="color: #DD0000">'mydbname'</span><span style="color: #007700">);<br /><br /></span><span style="color: #0000BB">?></span>
