Php 如何在symfony3中使用时区,php,symfony,Php,Symfony,我正在UTC时区中存储所有时间/日期时间。我想让用户指定他想在哪个时区查看小时/日期-就像在任何其他论坛（phpbb、ipb等…）到目前为止我所做的：在config.yml中，我设置了新的条令类型： types: datetime: AppBundle\DoctrineExtensions\DBAL\Types\UTCDateTimeType datetimetz: AppBundle\DoctrineExtensions\DBAL\Types\UTCDateTimeType

我正在UTC时区中存储所有时间/日期时间。我想让用户指定他想在哪个时区查看小时/日期-就像在任何其他论坛（phpbb、ipb等…）

到目前为止我所做的：

在

config.yml

中，我设置了新的条令类型：

types:
    datetime: AppBundle\DoctrineExtensions\DBAL\Types\UTCDateTimeType
    datetimetz: AppBundle\DoctrineExtensions\DBAL\Types\UTCDateTimeType
    time: AppBundle\DoctrineExtensions\DBAL\Types\UTCTimeType

例如，

UTDDateTime

：

<?php

namespace AppBundle\DoctrineExtensions\DBAL\Types;

use DateTime;
use DateTimeZone;
use Doctrine\DBAL\Platforms\AbstractPlatform;
use Doctrine\DBAL\Types\ConversionException;
use Doctrine\DBAL\Types\DateTimeType;

class UTCDateTimeType extends DateTimeType
{
    /** @var DateTimeZone */
    private static $utc;
    /** @var DateTimeZone */
    private static $defaultTimeZone;

    /**
     * @param DateTime $dateTime
     * @param AbstractPlatform $platform
     *
     * @return string|null
     */
    public function convertToDatabaseValue($dateTime, AbstractPlatform $platform)
    {
        if ($dateTime instanceof DateTime) {
            $dateTime->setTimezone(self::getUtc());
        }
        return parent::convertToDatabaseValue($dateTime, $platform);
    }

    /**
     * @param string $dateTimeString
     * @param AbstractPlatform $platform
     *
     * @throws ConversionException
     *
     * @return DateTime|null
     */
    public function convertToPHPValue($dateTimeString, AbstractPlatform $platform)
    {
        if (null === $dateTimeString || $dateTimeString instanceof DateTime) {
            return $dateTimeString;
        }
        $dateTime = DateTime::createFromFormat($platform->getDateTimeFormatString(), $dateTimeString, self::getUtc());
        if (!$dateTime) {
            throw ConversionException::conversionFailedFormat(
                $dateTimeString,
                $this->getName(),
                $platform->getDateTimeFormatString()
            );
        }
        // set time zone
        $dateTime->setTimezone(self::getDefaultTimeZone());
        return $dateTime;
    }

    /**
     * @return DateTimeZone
     */
    private static function getUtc()
    {
        return self::$utc ? self::$utc : self::$utc = new DateTimeZone('UTC');
    }

    /**
     * @return DateTimeZone
     */
    private static function getDefaultTimeZone()
    {
        return self::$defaultTimeZone
            ? self::$defaultTimeZone : self::$defaultTimeZone = new DateTimeZone(date_default_timezone_get());
    }
}

doctrine:
    dbal:
        types:
            utcdatetime:
                name: datetime
                class: AppBundle\Doctrine\DBAL\Types\UTCDateTimeType

并将我的

php.ini

配置为

UTC

。现在麻烦来了：

操作

date\u default\u timezone\u get（）。有什么办法让它工作吗？
你很接近了。实际上，您可以简化一点：
在config.yml
中，您只需覆盖datetime
：
<?php

namespace AppBundle\DoctrineExtensions\DBAL\Types;

use DateTime;
use DateTimeZone;
use Doctrine\DBAL\Platforms\AbstractPlatform;
use Doctrine\DBAL\Types\ConversionException;
use Doctrine\DBAL\Types\DateTimeType;

class UTCDateTimeType extends DateTimeType
{
    /** @var DateTimeZone */
    private static $utc;
    /** @var DateTimeZone */
    private static $defaultTimeZone;

    /**
     * @param DateTime $dateTime
     * @param AbstractPlatform $platform
     *
     * @return string|null
     */
    public function convertToDatabaseValue($dateTime, AbstractPlatform $platform)
    {
        if ($dateTime instanceof DateTime) {
            $dateTime->setTimezone(self::getUtc());
        }
        return parent::convertToDatabaseValue($dateTime, $platform);
    }

    /**
     * @param string $dateTimeString
     * @param AbstractPlatform $platform
     *
     * @throws ConversionException
     *
     * @return DateTime|null
     */
    public function convertToPHPValue($dateTimeString, AbstractPlatform $platform)
    {
        if (null === $dateTimeString || $dateTimeString instanceof DateTime) {
            return $dateTimeString;
        }
        $dateTime = DateTime::createFromFormat($platform->getDateTimeFormatString(), $dateTimeString, self::getUtc());
        if (!$dateTime) {
            throw ConversionException::conversionFailedFormat(
                $dateTimeString,
                $this->getName(),
                $platform->getDateTimeFormatString()
            );
        }
        // set time zone
        $dateTime->setTimezone(self::getDefaultTimeZone());
        return $dateTime;
    }

    /**
     * @return DateTimeZone
     */
    private static function getUtc()
    {
        return self::$utc ? self::$utc : self::$utc = new DateTimeZone('UTC');
    }

    /**
     * @return DateTimeZone
     */
    private static function getDefaultTimeZone()
    {
        return self::$defaultTimeZone
            ? self::$defaultTimeZone : self::$defaultTimeZone = new DateTimeZone(date_default_timezone_get());
    }
}

doctrine:
    dbal:
        types:

                name: datetime
                class: AppBundle\Doctrine\DBAL\Types\UTCDateTimeType



在UTCDateTimeType
中，您只需确保UTC日期时间存储在数据库中：

use Doctrine\DBAL\Types\DateTimeType;

/**

 */
class UTCDateTimeType extends DateTimeType
{
    /**
     * @var \DateTimeZone
     */
    private static $utc = null;

    /**
     * @param mixed            $value
     * @param AbstractPlatform $platform
     *
     * @return mixed
     */
    public function convertToDatabaseValue($value, AbstractPlatform $platform)
    {
        if ($value instanceof \DateTime) {
            $value->setTimezone(self::getUtc());
        }

        return parent::convertToDatabaseValue($value, $platform);
    }

    /**
     * @param mixed            $value
     * @param AbstractPlatform $platform
     *
     * @return $this|mixed
     * @throws ConversionException
     */
    public function convertToPHPValue($value, AbstractPlatform $platform)
    {
        if (null === $value || $value instanceof \DateTime) {
            return $value;
        }

        $converted = \DateTime::createFromFormat(
            $platform->getDateTimeFormatString(),
            $value,
            self::$utc ? self::$utc : self::$utc = new \DateTimeZone('UTC')
        );

        if (!$converted) {
            throw ConversionException::conversionFailedFormat(
                $value,
                $this->getName(),
                $platform->getDateTimeFormatString()
            );
        }

        return $converted;
    }

    /** @return \DateTimeZone */
    private static function getUtc()
    {
        if (self::$utc === null) {
            self::$utc = new \DateTimeZone('UTC');
        }

        return self::$utc;
    }
}
