if and elseif in PHP

Branching on a value with PHP's one-word elseif and the ternary.

<?php
$hour = 14;

// elseif is one word in PHP
if ($hour < 12) {
    $greeting = "good morning";
} elseif ($hour < 18) {
    $greeting = "good afternoon";
} else {
    $greeting = "good evening";
}

echo $greeting, PHP_EOL;
echo $hour >= 9 && $hour < 17 ? "office hours" : "closed", PHP_EOL;

How it works

1. The chain tests $hour against noon and 18:00, binding one greeting.
2. elseif is a single keyword in PHP, unlike the two-word forms elsewhere.
3. A ternary with && condenses the office-hours check to one line.
