随机问候函数-PHP - Randomised Greeting Function - PHP

因此，我用PHP创建了一个脚本，该脚本根据日期和时间设置问候语。该代码会检查是否有任何季节性事件，如果没有，则会检查时间并分配适当的问候语。我的问题是：

我已经设置了值来检查时间是否超过18:00，如果超过了这个时间，它应该设置一个晚上的问候语。我的问题是，如果我将来将php-if参数值更改为某个时间，它仍然将问候语作为晚间问候语。可能出了什么问题？

这是我的代码：

$morningGreetings = array(
    1 => "Good morning",
    2 => "Morning",
);
$standardGreetings = array(
    1 => "Hello",
    2 => "Howdy",
    3 => "Hiya",
    4 => "Greetings",
    5 => "Great to see you",
    6 => "Hi there",
    7 => "Hi",
    8 => "Good day",
);
$eveningGreetings = array(
    1 => "Evening",
    2 => "Good evening",
);
$seasonalGreetings = array( 
    1 => "Merry Christmas",
    2 => "Happy New Year",
);
$eventGreetings = array(
    1 => "Happy Birthday",
);
if (date("d m") != strtotime("25 12")) {
    if (date("d m") != strtotime("0 0")) {
        if (date("G i") <= strtotime("18 00")) {
            if (date("G i") <= strtotime("09 00")) {
                $sizeOfArray = sizeof($standardGreetings);
                $greetingValue = rand(1, $sizeOfArray);
                $greeting = $standardGreetings[$greetingValue];
            } else {
                $sizeOfArray = sizeof($morningGreetings);
                $greetingValue = rand(1, $sizeOfArray);
                $greeting = $morningGreetings[$greetingValue];
            }
        } else {
            $sizeOfArray = sizeof($eveningGreetings);
            $greetingValue = rand(1, $sizeOfArray);
            $greeting = $eveningGreetings[$greetingValue];
        }
    } else {
        $greeting = $seasonalGreetings[2];
    }
} else {
    $greeting = $seasonalGreetings[1];
}

也许是这样的：
