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
9
1
2
3
4
5
6
7
8
<?php
$age = 17;
if ($age >= 18) {
echo "You're an adult";
} else {
echo "You're not an adult yet.";
}
?>
12345678<?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 ( )
.
