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>

如果你使用Plesk,试试它,首先,打开PHP设置,在页面底部,更改日期。从DEFAULT到UTC的时区。

@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。

在你的连接页面中输入如下代码:date_default_timezone_set("Africa/Johannesburg");基于你当前的位置。

在index.php文件中添加以下内容。当我把我的应用程序从XAMPP服务器迁移到Apache 2.2和PHP 5.4时,我第一次遇到了这个问题……

我建议你在index.php文件中,而不是在php.ini文件中。

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

你可以在你的.htaccess文件中设置时区

php_value date.timezone UTC

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
