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

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

其他回答

我必须把它放在双引号里。

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

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

<? 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)

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。

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。
