PHP Warning: date(): It is not safe to rely on the system's timezone settings

转载自:http://blog.sina.com.cn/s/blog_5cd54bb40100n0tg.html

在用PHP5.3以上的PHP版本时,只要是涉及时间的会报一个

"PHP Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in"

这样的错。如何解决呢

实际上,从 PHP 5.1.0 ,当对使用date()等函数时,如果timezone设置不正确,在每一次调用时间函数时,都会产生E_NOTICE 或者 E_WARNING 信息。而又在php5.1.0中,date.timezone这个选项,默认情况下是关闭的,无论用什么php命令都是格林威治标准时间,但是PHP5.3中好像如果没有设置也会强行抛出了这个错误的,解决此问题,只要本地化一下,就行了。

以下是三种方法(任选一种都行):

一、在页头使用date_default_timezone_set()设置 date_default_timezone_set('PRC');  //东八时区 echo date('Y-m-d H:i:s');

二、在页头使用 ini_set('date.timezone','Asia/Shanghai');

三、修改php.ini。打开php5.ini查找date.timezone 去掉前面的分号修改成为:date.timezone =PRC

重启http服务(如apache2或iis等)即可。

XXX可以任意正确的值。对于我们国内来说:可以为以下值:Asia/Chongqing ,Asia/Shanghai ,Asia/Urumqi (依次为重庆,上海,乌鲁木齐)港台地区可用:Asia/Macao ,Asia/Hong_Kong ,Asia/Taipei (依次为澳门,香港,台北),还有新加坡:Asia/Singapore,当然PRC也行。

SURI (Schema URI) being unregistered in the "Settings > Languages & Frameworks > Schemas and DTDs" section typically refers to an issue where Visual Studio Code or a similar development environment is unable to locate or recognize a specific XML schema definition (XSD) file that is needed for validation, auto-completion, or other XML-related tasks. This error message usually occurs when you try to work with XML documents that rely on external schemas, and the system cannot find those schemas in its built-in or custom schema locations. Here's what might cause this problem: 1. Schema location: The XSD file might not be in the expected location, such as the project's `xsd` folder, or the `schemas` directory under your user settings. 2. Incorrect schema reference: The XML document might have a broken or incorrect `<schemaLocation>` or `<noNamespaceSchemaLocation>` element, causing VS Code to not know where to find the schema. 3. Missing extension or installation: If you have a custom extension for XML support, it could be missing the required configuration or the schema itself is not installed correctly. 4. VS Code settings: Ensure that the XML Tools or Language Features settings are configured to include the path where the schema files are located. To resolve this issue, you can try these steps: 1. **Check schema location**: Make sure the XSD file is present in the specified location. 2. **Update schema reference**: Edit the XML file and verify that the schema location URL is correct. 3. **Add schema to preferences**: In VS Code, navigate to `Preferences: User Settings` or `Code Settings (JSON)`, and add a new entry for `"xml.schemas"` with the complete URL of the schema file. 4. **Restart VS Code**: Sometimes, the change needs a restart to take effect. 5. **Reinstall or update extensions**: If using an extension, check for updates or reinstall it, if necessary. After trying these steps, you should be able to resolve the "SURI is not registered" error. If the issue persists, please let me know for further assistance.
