PHP Difference between empty and = ""

The empty() function checks whether a variable is empty, as defined here:

http://www.php.net/manual/en/function.empty.php

= "" sets a variable to an empty string.

Do you mean the difference between using empty() and == ""?

If so, there is a major difference.

$variable = 0;

if (empty($variable)) // true
if ($variable == "") // false
