php “date()：依赖系统的时区设置是不安全的......”

"date(): It is not safe to rely on the system's timezone settings..."

提问by user1852837

I got this error when I requested to update the PHPversion from 5.2.17 to PHP 5.3.21 on the server.

当我请求将服务器上的PHP版本从 5.2.17更新到 PHP 5.3.21时出现此错误。

You probably need to put the timezone in a configuration line in your php.inifile. You should have a block like this in your php.ini file:

您可能需要将时区放在php.ini文件的配置行中。你的 php.ini 文件中应该有一个这样的块：

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York

If not, add it (replacing the timezone by yours). After configuring, make sure to restart httpd (service httpd restart).

如果没有，请添加它（用您的时区替换时区）。配置完成后，一定要重启httpd( service httpd restart)。

Here is the list of supported timezones.

If you cannot modify your php.ini configuration, you could as well use the following snippet at the beginning of your code:

如果您无法修改 php.ini 配置，您也可以在代码开头使用以下代码段：

date_default_timezone_set('Africa/Lagos');//or change to whatever timezone you want

The list of timezones can be found at http://www.php.net/manual/en/timezones.php.

时区列表可以在http://www.php.net/manual/en/timezones.php找到。

Add the following in your index.phpfile. I first came across this when I moved my application from my XAMPPserver to Apache 2.2 and PHP 5.4...

在您的index.php文件中添加以下内容。当我将我的应用程序从我的XAMPP服务器移动到 Apache 2.2 和 PHP 5.4时，我第一次遇到了这个问题......

I would advise you do it in your index.phpfile instead of the php.inifile.

我建议你在你的index.php文件而不是php.ini文件中做。

if( ! ini_get('date.timezone') )
{
    date_default_timezone_set('GMT');
}

<? print(gmdate("Y")); ?> 

instead of

代替

<? print(date("Y")); ?>

worked for me (shows current year and no more shows the error message). (Thanks to Chris above)

为我工作（显示当前年份，不再显示错误消息）。（感谢上面的克里斯）

If these are not your options

如果这些不是您的选择

• Modifying php.ini.
• Adding date_default_timezonecall.

• 修改php.ini.
• 添加date_default_timezone呼叫。

Instead of dateyou could use gmdate.

而不是date你可以使用gmdate.

I have used gmdate( "Y" )when I needed a year for a copyright snipplet.

gmdate( "Y" )当我需要一年的版权片段时，我已经使用过。

If you are using CodeIgniter and can't change php.ini, I added the following to the beginning of index.php:

如果您使用的是 CodeIgniter 并且无法更改 php.ini，我在 index.php 的开头添加了以下内容：

date_default_timezone_set('GMT');

回答by Shaiful Islam

I always keep this line inside codeigniter's root index.php.So that my code works at any server

我总是将这一行放在 codeigniter 的根目录中index.php。这样我的代码就可以在任何服务器上运行

date_default_timezone_set('Asia/Dhaka');

@Justis pointed me to the right direction, but his code did not work for me. This did:

@Justis 为我指明了正确的方向，但他的代码对我不起作用。这做到了：

// set the default timezone if not set at php.ini
if (!date_default_timezone_get('date.timezone')) {
    // insert here the default timezone
    date_default_timezone_set('America/New_York');
}

Documentation: http://www.php.net/manual/en/function.date-default-timezone-get.php

文档：http: //www.php.net/manual/en/function.date-default-timezone-get.php

This solution is not only for those who does not have full system access. It is necessary for any script when you provide it to anyone else but you. You never know on what server the script will run when you distribute it to someone else.

此解决方案不仅适用于没有完整系统访问权限的人。当您将任何脚本提供给除您之外的任何其他人时，它对于任何脚本都是必要的。当您将脚本分发给其他人时，您永远不知道脚本将在哪个服务器上运行。

I had to put it in double quotes.

我不得不把它放在双引号中。

date_default_timezone_set("America/Los_Angeles"); // default time zone

This issue has been bugging me for SOME time as im trying to inject a "createbucket.php" script into composer and i keep being told my time-zone is incorrect.

这个问题一直困扰着我一段时间，因为我试图将“createbucket.php”脚本注入作曲家，但我一直被告知我的时区不正确。

In the end the only thing that fixed the issue was to: $ sudo nano /etc/php.ini

最后，解决问题的唯一方法是： $ sudo nano /etc/php.ini

Search for timezone

搜索时区

[Date]
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
date.timezone = UTC

Ensure you remove the ;

确保您删除 ;

Then finally

然后最后

$ sudo service httpd restart

And you'll be good to go :)

你会很高兴的:)
