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>Filename: libraries/Log.php</p>

我总是在codeigniter的根index.php中保留这一行，这样我的代码可以在任何服务器上工作

date_default_timezone_set('Asia/Dhaka');

此处支持的时区列表

我必须把它放在双引号里。

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

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

对于docker用户: 在你的项目中创建一个本地时区。ini文件，在docker-compose.yml中设置配置，

    volumes:
        - "./docker/config/timezone.ini:/usr/local/etc/php/conf.d/timezone.ini"

timezone.ini

    date.timezone=Australia/Sydney

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。

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 
?>
