However, sometimes just the IF statement isn't enough, you need the ELSE statement as well. When using just the IF statement the code within the brackets either will (true) or will not (false) be executed before carrying on with the rest of the program. When we add in the ELSE statement, if the statement is true it will execute the first set of code and if it is false it will execute the second (ELSE) set of code. Here is an example:
<?php
$over65=true;
$price = 3.00;
if ($over65)
{
$discount =.90;
print "You have received our senior's discount, your price is $" . $price*$discount;
}
else
{
print "Sorry you do not qualify for a discount, your price is $" . $price;
}
?>
