如何在PHP中将日期转换为时间戳? [英] How to convert date to timestamp in PHP?

问题描述

如何从例如22-09-2008?

推荐答案

此方法在Windows和Unix 上都可以使用，并且可以识别时区，如果您想要的话，这可能是您想要的使用日期.

This method works on both Windows and Unix and is time-zone aware, which is probably what you want if you work with dates.

如果您不关心时区，或者想使用服务器使用的时区:

If you don't care about timezone, or want to use the time zone your server uses:

$d = DateTime::createFromFormat('d-m-Y H:i:s', '22-09-2008 00:00:00');
if ($d === false) {
    die("Incorrect date string");
} else {
    echo $d->getTimestamp();
}

1222093324 _{(这取决于您的服务器时区...)}

如果要在哪个时区指定，请在此处EST. (与纽约相同.)

If you want to specify in which time zone, here EST. (Same as New York.)

$d = DateTime::createFromFormat(
    'd-m-Y H:i:s',
    '22-09-2008 00:00:00',
    new DateTimeZone('EST')
);

if ($d === false) {
    die("Incorrect date string");
} else {
    echo $d->getTimestamp();
}

或者如果您想使用 UTC . (与" GMT 相同.)

Or if you want to use UTC. (Same as "GMT".)

$d = DateTime::createFromFormat(
    'd-m-Y H:i:s',
    '22-09-2008 00:00:00',
    new DateTimeZone('UTC')
);

if ($d === false) {
    die("Incorrect date string");
} else {
    echo $d->getTimestamp();
}

无论如何，严格将字符串解析为结构化数据时始终是一个很好的起点.它可以节省以后的笨拙调试.因此，我建议始终指定日期格式.

Regardless, it's always a good starting point to be strict when parsing strings into structured data. It can save awkward debugging in the future. Therefore I recommend to always specify date format.
