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:

php

main

copy

              
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 ( ).
