Workaround for time zone problems encountered in PHP

Recently in the process of learning PHP found PHP format timestamp 8 hours later than Beijing time, internet search found that the original time zone is not correct, the solution is: 1. Permanent modification Change Data.timezone in php.ini file = PRC This is China time. The Apache service is restarted after the operation. 2. Temporary modification Add Ini_set (' Date.timezone ', ' Asia/shanghai ') before using the formatted input time; or Data_default_timezone_set (' PRC '); the//date_default_timezone_set () function sets the default time zone for all date/time functions used in the script. Look at the problems that other small partners have encountered One legacy of the previous problem is that echo date ("Y-m-d h:i:s", Time ()) is always back with the actual time, and today finally found the reason and solution on the Internet, share the following: Add a little, according to the method suggested below to modify php.ini can not find Date.timezone this line, is not there is no way, of course, no, haha no words on their own add, own hands and clothing. Add such a sentence Date.timezone = "PRC", the problem is done, happy Starting with php5.1.0, PHP.ini added the Date.timezone option, which is turned off by default That is, the time displayed (no matter what PHP command) is Greenwich Mean time, and our time (Beijing time) is about 8 hours, the following 3 methods can restore normal time. 1, the simplest way is not to use the version of php5.1 above 2, if must be used, and can not modify the php.ini, you need to be on the initialization of the time of the statement on the top plus date_default_timezone_set (XXX); 3, once and for all, can only modify php.ini. Open php.ini Find Date.timezone remove the preceding semicolon = Add xxx After, restart HTTP service (such as Apache2 or IIS, etc.) For XXX, the values available in mainland China are: asia/chongqing, Asia/shanghai, Asia/urumqi (Chongqing, Shanghai, Urumqi, respectively) Taiwan available: Asia/macao, Asia/hong_kong, Asia/taipei (Macau, Hong Kong, Taipei, respectively) and Singapore: Asia/singapore The foreigner seems to have missed Beijing's tune. Other available values are: Etc/gmt-8, Singapore, Hongkong, PRC What is PRC? PRC is the People's Republic of China Ah-_- ——————————————————————————————————————— Workaround: Use Date_default_timezone_set () in the header to set my default time zone to Beijing time Date_default_timezone_set (' PRC '); echo Date (' y-m-d h:i:s '); Time is the same as the current time of the server!! Congratulations on the attached Date_default_timezone_set usage as follows ——————————– Date_default_timezone_set (PHP 5 >= 5.1.0rc1) date_default_timezone_set-Setting the default time zone description for all datetime functions in a script BOOL Date_default_timezone_set (String timezone_identifier) Date_default_timezone_set () Sets the default time zone for all datetime functions. Note: Since PHP 5.1.0 (This version of the date time function is rewritten), each call to a DateTime function will produce an E_notice level error message if the time zone is not in law. Above mentioned above is the whole content of this article, hope everybody can like.
