$dbname = "my_db";
$conn=mysqli_connect($host,$username,$password,$dbname);
if(!$conn)
{
die('Could not Connect MySql Server:' .mysql_error());
}
?>
Step 2: Create Get Latitude and Longitude Form

<?php
require_once "db.php";
if (isset($_POST['submit'])) {
$lat = $_POST['lat'];
$long = $_POST['long'];
$sql = "SELECT * ,
(3956 * 2 * ASIN
(SQRT( POWER(SIN(
( $lat - LatOnTable) * pi()/180 / 2), 2)
+COS( $lat * pi()/180) * COS(LatOnTable * pi()/180)
* POWER(SIN(
( $long - LongOnTable) * pi()/180 / 2), 2) )))
as distance
from locations
having distance <= 10
order by distance";
$result = mysqli_query($conn, $sql);
}
?>
<?php
if (mysqli_num_rows($result) > 0) {
?>
<table class='table table-bordered table-striped'>
<tr>
<td>Address</td>
</tr>
<?php
$i=0;
while($row = mysqli_fetch_array($result)) {
?>
<tr>
<td><?php echo $row["address"]; ?></td>
</tr>
<?php
$i++;
}
?>
</table>
<?php
}else{
echo "No result found";
}
?>
</div>
</div>
</div>
</body>
