If Then Else
A if-then-else command branches the execution based on a condition. When the condition is true, the first branch, called then is executed. When the condition is false, the second branch, called else, is executed.
If-then structures may be chained with the elseif keyword. The else branch is then a new if-then structure, with a second condition.
<?php
$number = rand(0, 10);
if ($number % 2 === 0) {
print "$number is even\n";
} else {
print "$number is odd\n";
}
?>
