PHP Setting Time Zone method Introduction _php Tutorial

PHP default time zone is Europe and the United States, so with our Chinese time zone a full 8 hours, oh, let me introduce you to the PHP set time zone method, there is a need to know the friends can enter the reference.

In php.ini, the default is Date.timezone = UTC. Change to Chinese time zone, modified to Date.timezone = PRC. If you write the GMT format directly, it is Date.timezone = etc/gmt+8.

Alternatively, you can set it in the PHP page header.

The code is as follows	Copy Code
Date_default_timezone_set (' PRC ');

In PHP5, there are many ways to set or get the default time zone settings, for example, using the Date_default_timezone_setl function to set the time zone

The code is as follows	Copy Code
Date_default_timezone_set ("Asia/shanghain"); Set the time zone to Shanghai ?> or set the Tokyo time zone code to: Date_default_timezone_set ("Asia/tokyo"); ?> When the system is initialized, add Ini_set (' Date.timezone ', ' Asia/shanghai '); Or Date_default_timezone_set ("PRC");

Will resolve the time zone difference 8

And if you have php.ini administrative privileges can be modified directly in the php.ini OH

To manually modify php.ini settings

Open php found Date.timezone = "PRC" If you have to remove the previous semicolon, no words manually added!

After loading the PHP5 you will find this problem:

The code is as follows	Copy Code
$atime =date ("y-m-d h:i:s"); Echo $atime; ?> $atime =date ("y-m-d h:i:s"); Echo $atime; ?>

You may find that the output time is not the same as your current time.

The reason is that if you do not set your server local time zone in the program or configuration file, the time taken by PHP is Greenwich Mean time, so there will be a discrepancy with your local time.

Greenwich Mean Time and Beijing time is about 8 hours. So how do we avoid time errors?

Let's take a look at the workaround:

In the header, use Date_default_timezone_set () to set my default time zone to Beijing time.

The code is as follows	Copy Code
Date_default_timezone_set (' PRC '); echo Date (' y-m-d h:i:s '); ?>

The time is the same as the current time of the server.

Make sure that the H in date (' y-m-d h:i:s ') is uppercase if an Insert database error occurs.
