    <p>Im guessing that you need to iterate between the results and then echo them into the javascript.</p> <p>Im assuming you have the lat and lng stored in your database.</p> <pre><code>$coordinates = array(); $result = dbMySql::Exec('SELECT lat, lng FROM table WHERE id = 1'); while ($row = mysqli_fetch_assoc($result)) $coordinates[] = 'new google.maps.LatLng(' . $row['lat'] . ', ' . $row['lng'] . ')'; </code></pre> <p>And then on your javascript section</p> <pre><code>var flightPlanCoordinates = [ &lt;?php echo implode(',', $coordinates) ?&gt; ]; </code></pre> <p>Edit:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;?PHP class dbMySql { static function Exec($query) { // open database $conn = mysqli_connect('localhost','root','*****'); if($conn === false) { throw new Exception(mysqli_connect_error()); } mysqli_select_db($conn,'data_gps'); $result = mysqli_query($conn,$query); if(is_bool($result) &amp;&amp; !$result) { $error = mysqli_error($conn); mysqli_close($conn); throw new Exception($error); } //mysqli_close($conn); return $result; } } $coordinates = array(); $result = dbMySql::Exec('SELECT lat,lng FROM data'); while ($row = mysqli_fetch_assoc($result)) $coordinates[] = 'new google.maps.LatLng(' . $row['lat'] .

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).
