About PHP connection object
<p>Could somebody explain to me why the following is wrong :</p>

<pre><code>$sql='SELECT * FROM images';
$hostname ='localhost';
$username= 'root';
$password= '';
$db= 'myDB';

$numRows=new mysqli($hostname, $username, $password, $db)-&gt;query($sql)-&gt; num_rows;
</code></pre>

<p>The error throws is : syntax error, unexpected T_OBJECT_OPERATOR .....</p>

<p>and is it possible to correct it in one statement like above ? Thank you.</p>
