date():依赖系统的时区设置是不安全的…

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，我得到了这个错误。

<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>
<p>Message:  date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EDT/-4.0/DST' instead</p>
<p>Filename: libraries/Log.php</p>

在我的特殊情况下，我有PHP配置为使用PHP- fpm (FastCGI进程管理器)。当从CLI执行phpinfo()时，我看到了我在php.ini中设置的正确时区，但在浏览器中仍然不正确，导致我的代码失败。我只需要在服务器上重新启动php-fpm服务。

service rh-php56-php-fpm restart

如果您编辑了php.ini，则可能还需要重新启动httpd服务

service httpd restart

@Justis给我指出了正确的方向，但他的代码对我不起作用。这是:

// 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那些没有完全系统访问权限的人。当您将脚本提供给除您之外的任何人时，它对于任何脚本都是必要的。当您将脚本分发给其他人时，您永远不知道该脚本将在哪个服务器上运行。

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

而不是

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

为我工作过(显示当前年份，不再显示错误消息)。 (感谢上面的克里斯)

我已经在.htaccess文件中创建了这个:

php_value date.timezone Asia/Jakarta

但这并不奏效。然后我尝试将php版本从5升级到7。这就解决了问题。

你可以在你的.htaccess文件中设置时区

php_value date.timezone UTC

2018-01-18 21:41:20

<? date_default_timezone_set('Europe/Istanbul'); ?>

对于php(或您的位置)。
