Processing of date () Warning reported by the php Program (date_default_timezone_set)

Sometimes the following warning occurs when writing a php program:

PHP Warning: date (): It is not safe to rely on the system's timezone settings. you are * required * to use the date. timezone setting or the date_default_timezone_set () function. in case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. we selected 'utc' for '8. 0/no DST 'Instead in D: \ PHPWEB ews \ file. php on line 17.

This is because the time taken by PHP is Greenwich mean time, so there will be a difference between the GMT Standard Time and the Beijing time by about eight hours. We can solve this problem as follows:

1. Use date_default_timezone_set () in the page header to set my default time zone to Beijing time, that is, <? Php date_default_timezone_set ("PRC");?> You can.

2. in php. set date in ini. the value of timezone is PRC, and the value after setting is date. timezone = PRC or date. timezone = Asia/Shanghai, and cancel the comments of this line of code, that is, remove the semicolon.
