"date():依靠系统的时区设置是不安全的......"

Question

当我请求在服务器上将PHP版本从5.2.17 更新到PHP 5.3.21 时,我收到此错误.

<div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>

Answer 1

您可能需要将时区放在php.ini文件的配置行中.你应该在php.ini文件中有一个这样的块:

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

如果没有,请添加它(由您的时区替换).配置完成后,请确保重新启动httpd(service httpd restart).

以下是支持的时区列表.

Answer 2

如果您无法修改php.ini配置,您也可以在代码的开头使用以下代码段:

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

时区列表可在http://www.php.net/manual/en/timezones.php找到.

Answer 3

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

我建议你在你的index.php文件中而不是php.ini文件中进行.

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

Answer 4

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

代替

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

为我工作(显示当前年份,不再显示错误消息).(感谢克里斯上面)

Answer 5

如果这些不是您的选择

• 修改php.ini.
• 添加date_default_timezone电话.

而不是date你可以使用gmdate.

gmdate( "Y" )当我需要一年的版权信息时,我已经习惯了.

Answer 6

如果您正在使用CodeIgniter并且无法更改php.ini,我将以下内容添加到index.php的开头:

date_default_timezone_set('GMT');

Answer 7

我始终将这一行保留在codeigniter的根目录中index.php.因此我的代码可以在任何服务器上运行

date_default_timezone_set('Asia/Dhaka');

此处支持的时区列表

Answer 8

@Justis向我指出了正确的方向,但他的代码对我不起作用.这样做:

// 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');
}

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

此解决方案不仅适用于没有完整系统访问权限的用户.除了您之外,任何脚本都必须提供给任何其他人.当您将脚本分发给其他人时,您永远不知道脚本将在什么服务器上运行.

Answer 9

我不得不把它放在双引号中。

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

Answer 10

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，而且我一直被告知时区不正确。

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

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

确保删除 ;

然后最后

$ sudo service httpd restart

而且你会很好:)
