The php code with html below is showing a blank white screen when I open it with a web browser. I have set up a php server to run it. What am I doing wrong?

```
        <!DOCTYPE html>
        <html>
        <head>
                <title>maro</title>

                <div class="container-fluid">

            <div class="result">

                mysqli_select_db($_con,"websited");
                $_sql2="select * from webd where stitle like '%$search%'";
                $rs=mysqli_query($_con,$_sql2);
                if(mysqli_num_rows($rs)<1)
                                 {
                                  echo "<center><h4><b>Oops! No result found for your query</b></h4></center>";
                                  exit();
                                 }
                while($resul2=mysqli_fetch_assoc($rs))
                {
                    echo "<a href='".$resul2['slink']."'><img src='".$resul2['simg']."' height='200px' id="imgp"></a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
                }  
                ?>
            </div>
            <script src="jquery.min.js"></script>
            <script src="tether.min.js"></script>
            <script src="bootstrap.min.js"></script>
      </body>
</html>

```

I tried troubleshooting my php server but it's fine since other php codes are running perfectly. Please help fix this code
