About the PHP Program Report date () warning processing (date_default_timezone_set) _php tips

This warning is sometimes present in writing PHP programs:

PHP warning:date (): It isn't safe to rely on the system's timezone settings. You are are *required* to use the Date.timezone setting or the Date_default_timezone_set () function. In case you are used any of those methods and your are still getting this warning, for you most likely misspelled the timezone Iden Tifier. We selected ' UTC ' for ' 8.0/no DST ' instead in D:\PHPWEB ews\file.php on line 17.

This is because the time that PHP takes is Greenwich mean time, so and your local time will be difference between Greenwich Mean time and Beijing time is about 8 hours, we can follow the following method to solve:

1, in the header using Date_default_timezone_set () set my default time zone for Beijing, that is, <?php date_default_timezone_set ("PRC");?> on it.

2, in the php.ini set the value of Date.timezone for the PRC, set the following: DATE.TIMEZONE=PRC or Date.timezone = Asia/shanghai, while canceling this line of code comments, That is to remove the semicolon on the front.

Then restart Apache!
