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>

除了设定日期。Timezone =正如在几个答案中提到的，我在php.ini文件中发现了一个错误，它阻止它到达date.timezone。我找到它的方法是在终端的命令行中运行php。这导致在第114行报告一个错误。在我的例子中，我取消了显示两个值之间有“|”的错误的设置。它不喜欢这样。我删除了其中一个值和|，之后一切都很好

一个简单的方法，两个时区。

<?php 
$date = new DateTime("2012-07-05 16:43:21", new DateTimeZone('Europe/Paris')); 

date_default_timezone_set('America/New_York'); 

echo date("Y-m-d h:iA", $date->format('U')); 

// 2012-07-05 10:43AM 
?>

如果你不能访问php.ini文件，在你的域或子目录的根目录下创建或编辑一个。htaccess文件，并添加这个(由cpanel生成):

<IfModule mime_module>
AddType application/x-httpd-ea-php56 .php .php5 .phtml
</IfModule>

<IfModule php5_module>
php_value date.timezone "America/New_York"
</IfModule>

<IfModule lsapi_module>
php_value date.timezone "America/New_York"
</IfModule>

如果你正在使用CodeIgniter并且不能更改php.ini，我在index.php的开头添加了以下内容:

date_default_timezone_set('GMT');

您可能需要将时区放在php.ini文件的配置行中。你应该在你的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，添加它(用您的时区替换)。配置完成后，确保重新启动httpd (service httpd restart)。

下面是支持的时区列表。
