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>

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 
?>

其他回答

<? 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)

上面来自CtrlX的答案是正确的答案,但它可能不完全有效。 我在php.ini文件中添加了这一行:

date.timezone = "America/Los_Angeles"

但它没有删除所有文件的PHP错误,因为我的一些PHP脚本在子文件夹中。所以我必须编辑.htaccess文件来设置php.ini以递归地使用(在子文件夹中):

suphp_configpath /home/account_name/public_html

其中account_name是你的cpanel帐户名,public_html是你的php.ini文件所在的文件夹。

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

对于php(或您的位置)。

当你纠正不兼容时,一个快速的解决方案是禁用index.php文件中的错误报告:

将下面的行插入到你的index.php下面define(' _JEXEC ', 1);

error_reporting( E_ERROR | E_PARSE | E_CORE_ERROR | E_CORE_WARNING | E_COMPILE_ERROR |
E_COMPILE_WARNING );

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
