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>

当前回答

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。

其他回答

这个问题一直困扰我一段时间,因为我试图注入一个“createbucket.php”脚本到作曲家,我一直被告知我的时区是不正确的。

最后,解决这个问题的唯一方法是: $ sudo nano /etc/php.ini

搜索时区

[Date]
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
date.timezone = UTC

确保你移除;

最后

$ sudo service httpd restart

然后你就可以出发了:)

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 );

我在us-west-2(俄勒冈州)地区托管我的EC2和S3存储桶。当我调用$s3client->listBuckets()来列出我的php中现有的桶时,我得到了异常-“未捕获的异常'异常'与消息'DateTime::__construct():依赖系统的时区设置是不安全的…”。 我做了以下更改,使其工作。分享这些细节,以防有人面临类似的问题,以上任何答案都没有帮助。

Based on documentation @ AWS Configuring Network Time Protocol (NTP), I confirmed ntpd service status is fine by running ntpstat command. If you get error, this link helps you to know what is going wrong. Opened /etc/php.ini file (some may have it in different path based on version of php installed) and found that date.timezone was not set to any value and also it was commented by default. I un-commented by removing ';' before this line and set its value to "UTC" and saved the file. Restarted http and ntp daemons using sudo service httpd restart and sudo service ntpd restart commands.

在此之后,我能够成功地列出桶没有任何例外。希望这能有所帮助。

我必须把它放在双引号里。

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

@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');
}

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。
