PHP 101 (Part 2) - Shakespeare's Rose - If Not This, Then What?
(Page 6 of 9 )
In addition to the "if" statement, PHP also offers the "if-else" construct, used to define a block of code that gets executed when the conditional expression in the "if" statement evaluates as false.
The "if-else" construct looks like this:
if (condition)
{
do this!
}
else
{
do this!
}
As you can see, this construct can be used to great effect in
the last example - instead of two separate "if" statements, we can combine them into a single "if-else" statement.

I wonder if you've heard of Shakespeare, <? echo $name; ?>.
<p>
He postulated that a rose by any other name would smell just as sweet.

Unfortunately for you, I disagree. Access denied.
