随机问候语功能 - PHP

Question

所以，我在PHP中创建了一个脚本，它根据日期和时间设置问候语。代码检查任何季节性事件，如果没有，则检查时间并分配适当的问候语。我遇到的问题是：

我已设置值以检查时间是否超过18:00，如果超过此时间，则应设置晚上问候语。我的问题是，如果我将php if参数值更改为将来的某个时间，它仍会将问候语保持为晚间问候语。可能有什么不对？

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];

}
