Else Statement
An if
can be followed by an optional else
block. The else
block will execute if the Boolean expression tested by the if block evaluates to false
.
Let's consider a example:
main
<?php $age = 17; if ($age >= 18) { echo "You're an adult"; } else { echo "You're not an adult yet."; } ?>
In the example above, the age < 18, so the if code block hasn't been executed. The else
code block executes when the if condition is false
.
The else
syntax is like the if
syntax without a condition and parentheses ( )
.
Task
Fill in the blanks in the code to check the identity of variables $var1
and $var2
using the if ... else
construct.
