2022-07-24T19:00:00.000Z 是什么日期格式？

Question

I have this code running in my Kernel.php to blast an email at a set date:

$schedule->call(function () {BlastEmail::blastAll();})->hourly()->when(function() {
            $targetDate = strtotime(ENV('LAUNCH_COUNTDOWN'));
            $currentDate = strtotime(date("Y-m-d"));
            if($currentDate >= $targetDate) {
                return true;
            }
            return false;
        });

I realized that the format of $currentDate is Ymd, while the LAUNCH_COUNTDOWN I set is 2022-07-24T19:00:00.000Z. is this going to run successfully, or do I have to change the currentDate format? Thanks in advance.

Answer 1

You can use Carbon to parse it properly:

$schedule->call(function() {

})->hourly()->when(function() {
    $launchDate = Carbon::parse(env('LAUNCH_COUNTDOWN'));
    return Carbon::now()->greaterThan($launchDate);
});

This way the heavy lifting is done by Carbon. Note that this function will be called hourly till eternity after the given date.

Also, you shouldn't be calling env() in your code manually, as that function is designed to be called only in config files in [project]/config/someconfig.php so that it can be cached using php artisan config:cache . I know it is an easy thing to do but it's nicer to use something like:

file: config/project.php :

<?php
return [
    'launch_countdown' => env('LAUNCH_COUNTDOWN', false),
];

You then call app('project.launch_countdown') which defaults to false when the env variable is not set.
