自定义分钟的时间戳

Question

I would like to make custom timestamps. I need to round the minute of the time to 00 or 30. I made already a PHP code for this:

if (date("i") >= '15' && date("i") < '45') {
    $minute = "30";
}

else {
    $minute = "00";
}

But, now, I want to make the timestamp with the time + date in it.

Does someone have a solution for this? I think I'll need to use strptime but I don't know how exactly..

Answer 1

You can use mktime to generate a timestamp rounded to the nearest 30 minutes:

echo date('Y-m-d H:i:s', mktime(date('H'), round(date('i') / 30) * 30, 0));
