Article Introduction：The key to converting UTC time to local time in PHP is to use the DateTime class and the DateTimeZone class to combine operations. 1. The global time zone can be set through date_default_timezone_set, which is suitable for projects that use a certain time zone uniformly; 2. It is also recommended to use newDateTime to create a UTC time object and call the setTimezone method to convert it to the target time zone to avoid affecting the global settings; 3. When obtaining UTC time from the database, it can dynamically convert according to the user's time zone to achieve multi-time zone support; 4. Pay attention to the accurate time zone name, automatic processing of daylight saving time and formatted output methods. Mastering these methods can handle time conversion problems more stably and efficiently.
