Not changing the php time zone will cause the time of entering the database and the time of acquisition to be different from the actual time.

The solution to the time Zone problem encountered in PHP

Recently, when writing a Mini Program with PHP+MySQL, I found a problem: the difference between the time of entering the database and the actual time is 8 hours, which is consistent with the East 8 District of China. Since the database time is written by PHP, the problem occurs in PHP.

Recently, in the process of learning PHP, it was found that the formatting timestamp in PHP was 8 hours later than Beijing time. Online search found that it was the wrong time zone. The solution is:

1. Permanent modification

Change data.timezone = PRC in the php.ini file. This is China time. It takes effect after the Apache service is restarted.

2. Temporary modification

Add ini_set ('date.timezone','Asia/Shanghai') before entering time using formatting

Or the data_default_timezone_set ('PRC') / / date_default_timezone_set () function sets the default time zone for all date / time functions in the script.

Look at the problems encountered by other partners.

There was a remaining problem before, that is, the return time of echo date ("Y-m-d H:i:s", time ()) is always out of line with the actual time. Today, we finally found the reason and solution on the Internet, sharing as follows:

Add a point, according to the following tips to modify the php.ini can not find date.timezone this line, is there no way, of course not, , if not, then add it yourself, do your own food and clothing. With the addition of such a sentence date.timezone = "PRC", the problem is solved. Happy.

Starting with php5.1.0, date.timezone is added to php.ini, which is turned off by default

That is, the time displayed (no matter what php command is used) is Greenwich mean time, which is exactly 8 hours short of our time (Beijing time). There are three ways to return to normal time.

1. The easiest way is not to use a version above php5.1

2. If you must use it and you cannot modify php.ini, you need to add date_default_timezone_set (XXX) to the initialization statement about time.

3, once and for all, only php.ini can be modified. Open php.ini to find date.timezone and remove the previous semicolon

= add XXX after it, restart the http service (such as apache2 or iis, etc.)
