title: Undefined Index Error Reporting in WAMP and PHP
body: <p>I'm using wamp to develop a php application.  My problem is that everytime I call a variable that sometimes happens to not have a value, I get an error that says it's an undefined index.  Is there a way to change the error reporting to not display this error?  I have to use isset to determine if it's set or not before I output the variable, but I don't want to have to do this.  There are areas of my application that make this method inefficient.  </p>
