Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.

To convert United States (PST) time to China (CST) time, you can use PHP's built-in DateTime and DateTimeZone class functions.

The specific implementation is as follows:

// 创建美国时区的DateTime对象
$date = new DateTime('now', new DateTimeZone('America/Los_Angeles'));
// 设置新的目标时区为中国
$date->setTimezone(new DateTimeZone('Asia/Shanghai'));
// 输出中国时间
echo $date->format('Y-m-d H:i:s');

The idea of ​​​​this code is to first create a DateTime object to represent the current time ( That is, "now"), and set the time zone to Los Angeles, United States ('America/Los_Angeles'), then convert the time to the time zone of Shanghai, China ('Asia/Shanghai'), and finally output the formatted date and time information.

It should be noted that when creating a DateTime object, if the time zone is not specified, the local time zone of the server will be used. Therefore, be sure to explicitly specify the time zone by passing the second parameter to the function.

In addition, the format() method of DateTime can be used to format the time, in which the format string Y-m-d H:i:s means outputting the time in the format of year-month-day hour:minute:second.
