<?php
//connect database 
$con=mysqli_connect("localhost","root","","Employee") or die(mysqli_error());	  
//select values from empInfo table
$sql = "SELECT * from empInfo WHERE email='devesh@gmail.com'";
$result = mysqli_query($con,$sql);
print_r(mysqli_fetch_row($result));	
mysqli_close($con);
?>

Output : 
 Array(
			[0] =>1 
			[1] => devesh
