HomeBackend DevelopmentPHP TutorialPHP中设置时区方法小结_php技巧

找到原因后,在网上搜索到了一些关于PHP的时区设置方法:

1、修改php.ini,在php.ini中找到data.timezone =去掉它前面的;号,然后设置data.timezone = “Asia/Shanghai”;即可。

2、在程序PHP 5以上版本的程序代码中使用函数ini_set('date.timezone','Asia/Shanghai');或者date_default_timezone_set(‘Asia/Shanghai');

一些常用的时区标识符说明:

Asia/Shanghai – 上海
Asia/Chongqing – 重庆
Asia/Urumqi – 乌鲁木齐
Asia/Hong_Kong – 香港
Asia/Macao – 澳门
Asia/Taipei – 台北
Asia/Singapore – 新加坡


函数设置时区方法:

复制代码 代码如下:

function_exists(date_default_timezone_set);//在这他总是返回1,这函数是判断这里面的字符是不是一个定义了的函数名
date_default_timezone_set("Etc/GMT");//这是格林威治标准时间,得到的时间和默认时区是一样的
date_default_timezone_set("Etc/GMT+8");//这里比林威治标准时间慢8小时
date_default_timezone_set("Etc/GMT-8");//这里比林威治标准时间快8小时
date_default_timezone_set('PRC'); //设置中国时区
?>


函数ini_set()设置时区:
可以在文件开头加入 ini_set('date.timezone','Asia/Shanghai'); // 'Asia/Shanghai' 为上海时区

手动修改php.ini设置
打开php找到date.timezone = "PRC" 如有去掉前面的分号,没有的话手动添加!

以下是一些资料补充:

装上PHP5后你会发现这样的问题

$atime=date("Y-m-d H:i:s");
echo $atime;
?>
输出:2006-05-16 06:36:06
现在几点了?/我的是14:36
这是为什么捏?
原因是假如你不在程序或配置文件中设置你的服务器当地时区的话
PHP所取的时间是格林威治标准时间,所以和你当地的时间会有出入
格林威治标准时间和北京时间大概差8个小时左右 那么我们如何避免时间误差呢?
我们一起来看看解决方法:
在页头使用date_default_timezone_set()设置我的默认时区为北京时间
复制代码 代码如下:


date_default_timezone_set('PRC');
echo date('Y-m-d H:i:s');
?>

时间和服务器当前时间一样了!
另外附date_default_timezone_set用法如下:
------------------------------------------------------------------------------------
date_default_timezone_set
(PHP 5 >= 5.1.0RC1)
date_default_timezone_set -- 设定用于一个脚本中所有日期时间函数的默认时区
说明
bool date_default_timezone_set ( string timezone_identifier )
date_default_timezone_set() 设定用于所有日期时间函数的默认时区。
注: 自 PHP 5.1.0 起(此版本日期时间函数被重写了),如果时区不合法则每个对日期时间函数的调用都会产生一条 E_NOTICE 级别的错误信息。
参数
timezone_identifier
时区标识符,例如 UTC 或 Europe/Lisbon
返回值
本函数永远返回 TRUE(即使 timezone_identifier 参数不合法)。
-------------------------------------------------------------------------------------
或者修改 php.ini 中 date.timezone 值
date.timezone = PRC

装上PHP5后你会发现这样的问题
$atime=date("Y-m-d H:i:s");
echo $atime;
?>
输出:2006-05-16 06:36:06

What are Weak References in PHP and when are they useful?What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AM

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
