Answer 1

You may want to try using strict error reporting to see errors on your server and then use something like the ternary operator suggested by hsz. You will see all errors output in the browser window with the following line of code at the very top of your PHP script just below the first <?php

error_reporting(E_ALL ^ E_STRICT);

to turn error reporting off so you don't see errors use this instead.

error_reporting(0);

Answer 2

You should use isset in following way:

$Name = isset($_REQUEST['Name']) ? $_REQUEST['Name'] : '';

Answer 3

This can be solved by using hsz's method on another answer.

In the future PHP6 it would be

 $_REQUEST['Name'] = ifsetor($_REQUEST['Name'], "");

BTW do not use REQUEST array. It merges all $_COOKIE, $_GET, $_POST arrays into one. So your data can be overridden. Besides you never know is this $_REQUEST['NAME'] is coming from GET request or POST request or from COOKIE.
