    <p><strong>Yes it can be implement in a much better way</strong>. As you are using same <code>Database connection configuration</code> every-time, there is <strong>no need to connect and close database on page refresh</strong>.<em>Connecting to database server every-second is very expensive call</em>.</p> <p>Why don't you <code>just reload/refresh the query statement</code>?</p> <p>The idea is:</p> <p>Use <a href="http://php.net/manual/en/features.persistent-connections.php" rel="nofollow noreferrer">Persistent Database Connection</a></p> <p>Refer <strong>BlaM</strong> answer in following <a href="https://stackoverflow.com/questions/50303/persistent-db-connections-yea-or-nay">post</a> to know why persistent connections is optimal. </p> <p>Put the queries in a separate div say #load.</p> <pre><code> echo '&lt;div id="load"&gt;'; // SELECT sql query $sql = "SELECT * FROM `Value`"; // perform the query and store the result $result = $conn-&gt;query($sql); if (!$result) print 'Error!'; // if the $result contains at least one row if ($result-&gt;num_rows &gt; 0) { // output data of each row from $result while($row = $result-&gt;fetch_assoc()) { $output=$row; print_r($output); } } else { print '0 results'; } echo '&lt;/div&gt;'; </code></pre> <p>Use jquery function to <strong>refresh only #load div</strong></p> <pre><code>&lt;script type="text/javascript"&gt; var auto_refresh = setInterval( function () { $("#load").load("filename.php #load"); }15000); // refresh every 1 second &lt;/script&gt; </code></pre> <p><strong>I had implemented this for auto-refresh leaderboard page.It worked perfectly and server didn't crash even in 50 hrs</strong>.</p>

    2. COThis doesn't keep the MySQL connection alive. It still makes a new connection every refresh. bestprogrammerintheworld's answer is correct.

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
