I'm sure that this code can be written more efficient, please tell me how, but that's not my problem. The problem is that when i run this script all lines are executed. I'm sure I'm doing something wrong, but can't find out just what.

<?php
if (isset($variable))
{
        if ($variable < $constant)
        {
        Execute this code if $variable is less than $constant
        }
        if ($variable > $constant)
        {
        Execute this code if $variable is more than $constant
        }
        if ($variable == $constant)
        {
        Execute this code if $variable and $constant are equal
        }
}
else
{
Execute this code if $variable is not set
}
?>

Thanks for all help!
