Grab single value from mysql database with php

Russelauto asked
Last Modified: 2013-12-12
I'm using the following code to grab and store a value from a table in a mysql database.

  $result = mysql_query(" SELECT email FROM users WHERE username = '$username' ");
  $row = mysql_fetch_array($result);
  $email = $row["email"];
It works fine but my question is why do I have to fetch it from an array? Shouldn't it be a single non-array value? Shouldn't the value of $result be the email address?
