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!
