$rows = mysqli_num_rows($result);
$content = '<div class="row">

</div>
View Doctors <i class="fa fa-arrow-circle-right"></i>

Answer 1

You should use mysqli object in new php version try the following code
Make connection first like
<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");
$result = mysqli_query($con,"SELECT * FROM doctors");
$rows = mysqli_num_rows($result);
echo "There are " . $rows . " rows in my table.";
$content = '<div class="row">
<div class="col-lg-3 col-xs-6">
<!-- small box -->
<div class="small-box bg-aqua">
<div class="inner">
*<h3><?php echo "$rows"; } ?></h3>*
<p>Doctors</p>
</div>
<div class="icon">
<i class="ion ion-bag"></i>
</div>
View Doctors <i class="fa fa-arrow-circle-right"></i>
</div>
</div>
<!-- ./col -->
</div>';
include('../master.php');
?>

Answer 2

if you just need the count then why don't you use the aggregate function count(*) in your query. this much better helps you. and in your code in h3 tag you can concat the string directly rather than using again php code. this might looks better and in structured form.
try this:
<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");
$result = mysqli_query($con,"SELECT count(*) as total_rows FROM doctors");
$rows = $result->total_rows;
echo "There are " . $rows . " rows in my table.";
$content = '<div class="row">
<div class="col-lg-3 col-xs-6">
<!-- small box -->
<div class="small-box bg-aqua">
<div class="inner">
*<h3>'.$rows.'</h3>*
<p>Doctors</p>
</div>
<div class="icon">
<i class="ion ion-bag"></i>
</div>
View Doctors <i class="fa fa-arrow-circle-right"></i>
</div>
</div>
<!-- ./col -->
</div>';
include('../master.php');
?>
